A multi-resolution computational method to solve highly non-linear inverse scattering problems

Journal of Physics: Conference Series 2020年第1期1476卷

作者： Marco Salucci Alessandro Polo Kuiwen Xu Yu Zhong ELEDIA Research Center (ELEDIA@UniTN - University of Trento) I-38123 Trento Italy Key Lab of RF Circuits and Systems of Ministry of Edu ation Hangzhou Dianzi University Hangzhou China Institute of High Performance Computing A*STAR Singapore

An innovative computational method to solve inverse scattering problems is proposed for retrieving the electromagnetic properties of unknown targets. The proposed technique is based on the contraction integral equation for inversion (CIE-I) method to mitigate multiple scattering contributions when imaging strong scatterers. More specifically, the CIE-I is integrated in an effective multi-resolution (MR) scheme to reduce the ratio between unknowns and non-redundant data as well as to exploit iteratively acquired information on the scenario for yielding higher-resolution reconstructions. Some preliminary numerical results are reported to assess the capabilities of the proposed MR-CIE-I method.

A compact dual-frequency antenna with two-port excitation and large frequency ratio is presented. It consists of a circularly-polarized (CP) microstrip patch antenna at 2.4 GHz and a linearly-polarized (LP) substrate-integrated cylindrical dielectric resonator antenna (DRA) at 60 GHz, resulting in a large frequency ratio of as high as 25. The two antenna parts are designed on a single substrate, giving a very compact structure. Slot-coupled source and probes are used to excite the upper-band DRA and the lower-band patch antenna, respectively. ANSYS HFSS was used to simulate the S-parameters, radiation patterns, antenna gains, and axial ratio (AR) (patch antenna part only) of the two antenna parts. The lower-band patch antenna has an impedance bandwidth of 17.3% and AR bandwidth of 15.3%, whereas the upper-band has an impedance bandwidth of 13.15%. © 2017 IEEE.

A tunable high-impedance surface (HIS) based on hybrid metal-graphene structure is presented for terahertz (THz) applications. Its tunable properties and relative performance are studied by the proposed LE-FDTD method. At the same time, the equivalent circuit model is derived to give a theoretical explanation. Good performance is obtained in terms of bandwidth, gain, and tunability. The proposed structures are practical and potential for THz applications.

A 60 GHz fully differential power amplifier (PA) based on microstrip line (MSL) is presented in this paper. To accelerate design and characterization in EDA simulators circuit simulations, an equivalent substrate model extraction method for MSL is introduced. A differential three-stage cascode PA prototype is implemented in 65-nm bulk CMOS process for demonstration. The proposed PA has a 3-dB bandwidth ranging from 50 to 61 GHz, and generates saturation output power of 11.7 dBm with 20 dB gain, at 60 GHz. The test and simulation results agree well, indicating the effectiveness of the extracted model. This MSL model based design approach will pave a quick way for millimeter-wave power amplifier designs. © 2016 IEEE.

In this paper, metasurface-based antennas have been analyzed by multilevel Green's function interpolation method (MLGFIM). Layered medium Green's function is used as the kernel to efficiently reduce the number of unknowns. Interpolation of this type of Green's function is then implemented by radial basis functions (RBFs). The interpolation accuracies using Lagrange and RBF interpolations have been compared. A numerical example of a holographic antenna has been given to validate the accuracy and efficiency of the proposed method.
