An EM-CKT simulator for analyzing transient scattering from nonlinearly loaded periodic structures

Periodic arrangements of nonlinearly loaded scatterers (unit cells) are important components in phased array antenna systems, frequency selective surfaces, metamaterials, etc. For instance, metamaterials loaded with non-Foster circuits can exhibit enhanced bandwidth of operation (P.-Y. Chen, C. Argyropoulos, and A. Alu, Phys. Rev. Lett., 2013).
