Dgtd algorithm
WebMoreover, the CPU and memory costs are also compared, demonstrating clear advantages of the proposed prism-based DGTD method. AB - In this letter, we develop a prism-based discontinuous Galerkin time-domain (DGTD) algorithm with simplified periodic boundary conditions (PBCs) to analyze infinite doubly periodic frequency selective surfaces (FSS). WebThe rest of the paper is organized as follows. In Section 2, the theory of the DGTD method is introduced. In Sections 3 and 4, the algorithms of dynamic mesh adaptation and LTS are described, respectively. Section 5 presents numerical examples to validate the proposed method and demonstrate the capability of the DGTD solver with ACM and LTS ...
