Abstract Details

2023, Doctor of Philosophy, Ohio State University, Electrical and Computer Engineering.
A complete procedure of dealing with frequency-selective surfaces (FSS) in electromagnetic is addressed in this dissertation, including automatic design and fast numerical simulation. The design of the FSS contains the design of periodic structure and the arrangement of the periodic structure on an arbitrary platform. For the design of periodic structure, an adaptive artificial neural network (ANN) is presented herein to meet the desired frequency response automatically. Afterward, the designed periodic structure is arranged on an arbitrary platform by some seed points to approximate the locations, and the generation of seed points uses some electrons reaching an electrostatic distribution. For the fast numerical simulations of FSS, a generalized transition condition (GTC) is presented herein to reduce computation resources of both memory computation time due to the complex geometry. In this method, GTC serves as a field relationship to represent the electromagnetic interaction effect from the original FSS. The proposed GTC is inspired by the generalized sheet transition condition (GSTC) but gets rid of the zero-thickness assumption to build a relationship between the electric field and magnetic field on both sides of the FSS. The process of the proposed numerical simulation method of FSS includes three steps. The first is to obtain the reflection and transmission coefficients by the numerical simulation of FSS as an infinite periodic structure with periodic boundary conditions (PBC). Secondly, a self-consistent scheme is adopted to compute the coefficient in GTC with a required order. Finally, the constructed GTC can be used to replace the FSS in a real model. The collaboration of GTC with both surface integral equation (SIE) method and finite element method (FEM) are addressed in this dissertation. Especially for FEM, GTC is modified to bypass the edge effects and results in a conformal mesh on both sides of the transition condition. The accuracy of the proposed method is demonstrated through multiple examples.
