In this paper, we demonstrate six types of metamaterial absorbers （MMAs） by measuring their absorptivities in an X-band （8 12 GHz） rectangular waveguide. Some of the MMAs have been demonstrated previously by using the free space measurement method, and the others are proposed firstly in this paper. The measured results show that all of the six MMAs exhibit high absorptivities above 98%, which have similar absorbing characteristics to those measured in the free space. The numerically obtained surface current densities for each MMA show that the absorbing mechanism is the same as that under the free space conditions. Such a demonstration method is superior to the conventional free space measurement method due to the small-scale test samples required, the simple measure device, and its low cost. Most importantly, the proposed method opens a way to enable MMAs to be used in microwave applications such as matched terminations.

This paper presents a study of and triboson production using events from proton-proton collisions at a centre-of-mass energy of recorded with the ATLAS detector at the LHC and corresponding to an integrated luminosity of 20.2 fb . The production cross-section is determined using a final state containing an electron, a muon, a photon, and neutrinos ( ). Upper limits on the production cross-section of the final state and the and final states containing an electron or a muon, two jets, a photon, and a neutrino ( or ) are also derived. The results are compared to the cross-sections predicted by the Standard Model at next-to-leading order in the strong-coupling constant. In addition, upper limits on the production cross-sections are derived in a fiducial region optimised for a search for new physics beyond the Standard Model. The results are interpreted in the context of anomalous quartic gauge couplings using an effective field theory. Confidence intervals at 95% confidence level are derived for the 14 coupling coefficients to which and production are sensitive.

Partially coherent light interaction with nano objects

Scattering of fully coherent light from nano objects is a very matured field with plethora of applications. However, due to various fundamental and operational reasons, fluctuations in various characteristic features of interacting light fields cannot be fully suppressed. Such light fields with random fluctuating features are known as partially coherent light. When partially coherent light interact with nano-objects (i.e. solids or voids), new characteristics emerge (e.g. coherence vortex, fully-incoherent point-pairs) that are absent in fully coherent scattered fields. In this paper, we review the fundamental metrics for characterising partially coherent light and how such metrics can be used to reveal some of the hidden features of partially coherent light interacting with nano-objects.

The research of metamaterial is one of most important global activity that promises to change the lives in many different ways. Flexibly controlling the properties of metamaterials by tunable designs makes metamaterials more colorful and thus enables a family of new electromagnetic devices. In this paper, the use of ferrites on design of tunable metamaterials has been reviewed. Owing to the novel properties of ferrites, including broadband negative permeability and tunability of permeability, a great many researchers have focused on investigating ferrites based metamaterials and the relevant applications. This paper reviews the design, theoretical analysis, numerical and experimental demonstrations, and the potential applications of the ferrite based metamaterials.

Modified Iterative-Learning-Control-Based Ramp Metering Strategies for Freeway Traffic Control With Iteration-Dependent Factors

IEEE Transactions on Intelligent Transportation systems 2012年第2期13卷 606-618页

作者： Zhongsheng Hou Jingwen Yan Jian-Xin Xu Zhenjiang Li Advanced Control Systems Laboratory of School of Electronic and Information Engineering Beijing Jiaotong University Beijing China Department of Electrical and Computer Engineering National University of Singapore Singapore Key Laboratory of Complex Systems and Intelligence Science Institute of Automation Chinese Academy of Sciences Beijing China

For a freeway traffic system with strict repeatable pattern, iterative learning control (ILC) has been successfully applied to local ramp metering for a macroscopic freeway environment by formulating the original ramp metering problem as an output tracking, disturbance rejection, and error compensation problem. In this paper, we address the freeway traffic ramp-metering system under a nonstrict repeatable pattern. ILC-based ramp metering and ILC add-on to ALINEA strategies are modified to deal with the presence of iteration-dependent parameters, iteration-dependent desired trajectory, and input constraints. Theoretical analysis and extensive simulations are used to verify the effectiveness of the proposed approaches.

We present a tunable triple-band μ-negative metamaterial composed of loop resonator and ferrite. The tunable triple-band-stop transmission spectrum of such metamaterial is investigated numerically by full wave simulations. Moreover, the corresponding effective parameters are retrieved to illustrate the tunable μ-negative characteristic.

This paper presents an alternative approach, based on the transmission line theory, for determination of the attenuation constant (α), phase constant (β), characteristic impedance (Zo), refractive index (n), effective permittivity (ε) and effective permeability (μ) for active transmission line (TL) metamaterial. When active elements are introduced into the lossy TL meta-material, the gain acquired from the active elements should be evaluated quantitatively against the attenuation due to the loss in order to avoid ambiguities in determining the signs of the effective constitutive parameters. In stead of directly determining the characteristic impedance from S-parameters, we introduce the reflection coefficient as an intermediate quantity to assist solving the characteristic impedance. This paper shows demonstration of this method with an example of active TL metamaterial.

Memristors have been rediscovered recently and then gained increasing attentions. Their unique properties, such as high density, nonvolatility, and recording historic behavior of current (or voltage) profile, have inspired the creation of memristor-based neuromorphic computing architecture. Rather than the existing crossbar-based neuron network designs, we focus on memristor-based synapse and the corresponding training circuit to mimic the real biological system. In this paper, first, the basic synapse design is presented. On top of it, we will discuss the training sharing scheme and explore design implication on multi-synapse neuron system. Energy saving method such as self-training is also investigated.

Fluorescence has become a widely used technique for applications in noninvasive diagnostic tissue spectroscopy. The standard model used for characterizing fluorescence photon transport in biological tissue is based on the diffusion approximation. On the premise that the total energy of excitation and fluorescent photon flows must be conserved, we derive the widely used diffusion equations in fluorescence spectroscopy and show that there must be an additional term to account for the transport of fluorescent photons. The significance of this additional term in modeling fluorescence spectroscopy in biological tissue is assessed.
