In this paper, frequency selective surface (FSS) with relative zero-phase shift is realized and characterized. The FSS unit cell is designed by adding cross aperture to the cross loop slot at its center, and the four ends are placed by Y-shaped slots. Compared with normal FSS, the FSS with the relative zero-phase shift avoid the aberrance of the main lobe direction on the radiation pattern of antenna, when the FSS is designed for the radome. Numerical simulations are carried out to validate wider bandwidth and better angle stability. It is a miracle that the epsilon-near-one(ENO) metamaterial properties are presented, so the screen of these FSSs have many properties similar to air. The near-field and far-field are almost not affected by the screen for the cylindrical wave. © 2012 IEEE.

In this paper, a zero index metamaterial lens (ZIML) based on Z-shaped meta-atom is proposed to achieve directive emission. Z-shaped meta-atom is implement as the unit cell of the ZIML to achieve near zero permittivity for wideband. Patch antennas work at, respectively, 7.27 GHz, 8.02 GHz and 9.14GHz are used to test the directivity enhancement of the ZIML. Simulation results demonstrate that the ZIML we designed is able to significantly improve the directivity of the patch antennas. © 2012 IEEE.

An effective text representation scheme dominates the performance of text categorization system. However, based on the assumption of independent terms, the traditional schemes which tediously use term frequency （TF） and document frequency （DF） are insufficient for capturing enough information of a document and result in poor performance. To overcome this limitation, we investigate exploring the relationships between different terms of the same class tendency and the way of measuring the importance of a repetitive term in a document. In this paper, a group of novel term weighting factors are proposed to enhance the category contribution for each term. Then, based on a novel strategy of generating passages from document, we present two schemes, the weighted co-contributions of different terms corresponding to the class tendency and the weighted co-contributions for each term in different passages, to achieve improvements on text representation. The prior scheme works in a dimensionality reduction mode while the second one runs in the conventional way. By employing the support vector machine （SVM） classifier, experiments on four benchmark corpora show that the proposed schemes could achieve a consistent better performance than the conventional methods in both efficiency and accuracy. Further analysis also confirms some promising directions for the future works.

Antenna lens can obviously eincrease the gain of the antenna by method of gathering. Also, metamaterial lens can achieve the gathering effect with aspheric surface. In this paper, a new type of metamaterial lens is designed. It is easy to identify as Left-hand material with double negative electromagnetic constant, realizing a negative permittivity and a negative permeability simultaneously. The new structure can perform at a lower frequency and the band of the structure can get a good result in broad band. In addition, the new proposed metamaterial lens do not change the S-parameter of the original antenna. The gain can be increased by 2 dB with the new structure of the metamaterial lens. © 2012 IEEE.

In this paper, three types of EIT metamaterials are presented and numerically investigated. The type I metamaterial consists of the SR and the SRR, which are coupled with each other and assigned as the dark resonator and the radiative resonator, respectively. The metamaterial can exhibit EIT effect to both normally and laterally incident electromagnetic waves because of its electric and magnetic response, respectively. The type II magnetic metamaterial consists of the split ring resonator (SRR) and the spiral resonator (SR) along two orthogonal axes. For the excitation with the magnetic field perpendicular to the SRR plane, the SRR and the SR are designated as the radiative element and the dark element, respectively. A transparency window is observed in the overlapped absorption band of the independent resonator because of the destructive interference between the radiative and dark resonators of the metamaterial. The type III metamaterial is consisted of three cut wires of different sizes and parallel to each other. The resonance frequencies are different because the lengths of three metal wires are different. Under the polarization of electrical field, because three cut wires experience strong resonance, two-two overlaps of absorption bands of three cut wires will induce two transparency windows. Numerical simulations are carried out to validate the three types of EIT metamaterials, and the results have proven to be quite effective. © 2012 IEEE.

Multi-hop time synchronization in wireless sensor networks (WSNs) is often time-consuming and error-prone due to random time-stamp delays for MAC layer access and unstable clocks of intermediate nodes. Constructive interference (CI), a recently discovered physical layer phenomenon, allows multiple nodes transmit and forward an identical packet simultaneously. By leveraging CI, we propose direct multi-hop (DMH) time synchronization by directly utilizing the time-stamps from the sink node instead of intermediate nodes, which avoids the error caused by the unstable clock of intermediate nodes. DMH doesn't need decode the flooding time synchronization beacons. Moreover, DMH explores the linear regression technique in CI based time synchronization to counterbalance the clock drifts due to clock skews. © 2012 ACM.
