Reflectarray surface printed elements

Analysis and Optimisation of Quasi-Periodic Frequency Selective Surfaces (FSS) for reflectarray design is supported through TICRA’s QUPES software. This is a dedicated electromagnetic software tool for the analysis and design of quasi-periodic surfaces such as reflectarrays, frequency selective surfaces (FSS), transmitarrays, etc. The main features of QUPES include analysis and optimisation of scattering parameters of periodic unit cell structures; a predefined library of commonly used geometries; dedicated methods for the analysis of periodic/quasi-periodic surfaces; features for multiple panels, holes, planar and curved surfaces and large-scale direct optimisation of quasi-periodic surfaces for goals on primary as well as secondary patterns.
