In this study, the finite element method was used to analyze the scattering issue caused by various types of 3D structures coated with dielectrics on perfect electric conductors. To analyze the electromagnetic wave scattering problem, we implemented an in-house finite element analysis code based on the generalized Riesz principle, which is applicable to a wide range of electromagnetic boundary value problems. Through various numerical experiments, the accuracy and validity of the algorithm was verified. During this process, we identified and resolved the problems that occur when the number of elements is insufficient. [ABSTRACT FROM AUTHOR] |
