Modular modeling and optimization for large antenna arrays

In the next-generation phased-array systems, a closely packed system of RF functions and electronics is expected. This creates a need for both accurate and flexible design tools. We employ the generalized scattering matrix (GSM) formalism to arrive at a flexible tool with modest computational costs to enable a computer-aided design trajectory. We employ an integral equation technique to generate the scattering matrices and discuss some optimization strategies that seem appropriate for the type design problem that is obtained via the GSM formalism.
