Full-Wave Simulation of Time Modulated Linear Antenna Arrays in Frequency Domain

An effective frequency domain full-wave approach is proposed for the simulation of time modulated (TM) linear arrays with variable aperture size (VAS) time schemes. The full-wave simulation of the TM linear arrays is fulfilled by combination of the frequency domain full-wave simulation results of the corresponding regular linear arrays at multiples of the modulation frequency. Numerical simulation results of two TM linear arrays with VAS time schemes are presented and are compared with reported measurement results, and close agreement is obtained through comparison.
