PSSFSS-An Open-Source Code for Analysis of Polarization and Frequency Selective Surfaces

PSSFSS is a free, open-source code for analysis and design of polarization selective surfaces (PSSs), frequency selective surfaces (FSSs), radomes, reflectarray elements, and similar devices. It is written in Julia, a recently developed language for high-performance technical computing. Its speed and ease of use make PSSFSS useful and accessible to both students and working engineers. This paper describes the design of PSSFSS and provides several examples of its use, with comparisons to results from other simulation tools.
