Abstract
This paper presents a parallelized version of cascading procedure for analyzing the frequency selective surface (FSS) system comprising of multiple FSS screens of unequal periodicity embedded in multiple dielectric layers. The parallelism is implemented for computation of the [S] matrices of subsystems at the global harmonics, while the cascading operation (matrix calculations) is carried out in a single processor. The workload distribution among the processors is dynamic varying from subsystem to subsystem, and it is determined once the number of processors for the simulation is assigned. Besides the workload distribution that affects the performance of the parallel implementation, another factor is the ratio of amount of time needed for matrix/cascading operation to that required for the subsystem analysis for a single incident angle
