Generalized FDTD numerical modeling of space-time-varying media
Generalized FDTD numerical modeling of space-time-varying media
This paper presents a comprehensive study on the generalized Finite Difference Time Domain (FDTD) numerical modeling of linear and nonlinear space-time-varying microwave components. We investigate the dynamic behavior of media where electrical permittivity, magnetic permeability, and electrical conductivity are all subjected to modulation over both space and time. The FDTD scheme and equations for both TE and TM wave illuminations of space-time-varying slabs are provided. Additionally, intriguing illustrative examples are presented, including the multi-beam-multi-frequency generator and pure beam-splitting frequency generation for TE wave incidence, as well as the antenna-mixer-amplifier, nonreciprocal slab, and nonreciprocal beamsplitter for TM wave incidence. Through these examples, we showcase the versatility and potential applications of space-time-varying microwave components in modern communication systems, and quantum computing.

Abstract
This paper presents a comprehensive study on the generalized Finite Difference Time Domain (FDTD) numerical modeling of linear and nonlinear space-time-varying microwave components. We investigate the dynamic behavior of media where electrical permittivity, magnetic permeability, and electrical conductivity are all subjected to modulation over both space and time. The FDTD scheme and equations for both TE and TM wave illuminations of space-time-varying slabs are provided. Additionally, intriguing illustrative examples are presented, including the multi-beam-multi-frequency generator and pure beam-splitting frequency generation for TE wave incidence, as well as the antenna-mixer-amplifier, nonreciprocal slab, and nonreciprocal beamsplitter for TM wave incidence. Through these examples, we showcase the versatility and potential applications of space-time-varying microwave components in modern communication systems, and quantum computing.
