A multidomain Legendre pseudospectral frequency-domain method with penalty scheme for solving maxwell's equations

Abstract

A new multidomain pseudospectral frequency-domain (PSFD) method based on Legendre polynomials with a penalty scheme for studying electromagnetic wave scattering is presented. Scattered field calculation with accuracy on the order of 9 10  is obtained for a circular plasmonic cylinder. The method is further applied to demonstrate the scattering by a dielectric rectangular cylinder with sharp corners and by multiple circular plasmonic cylinders.

Basic Study on the Radio Frequency Characteristics of the Transmission Lines Employing Periodically Perforated Ground Metal on GaAs Monolithic Microwave Integrated Circuit and Their Equivalent Ciruits

“…For a simple circuit simulation, an extraction of equivalent circuit is indispensable, because full-wave EM simulation requires a lot of simulation time. [26][27][28][29][30][31][32][33][34] Especially, full-wave EM simulation in multi-layer metal structure such as PPGM makes the design process very complicated. To solve this problem, RLC equivalent circuit [35][36][37][38][39][40][41][42] should be extracted.…”

“…In spite of the an error range of 8.8-10.1%, the equivalent circuit proposed in this paper is the most efficient method to analyze the PPGM structure, because there is no equivalent circuit of PPGM in the commercial Advanced Design System (ADS) tool due to its very complicated structure of PPGM and three-dimensional (3D) full-wave analysis requires a lot of simulation time.
