Simulation of nonlinear hybrid circuit by FDTD

Make full-wave analysis of micro-strip low pass filter and nonlinear hybrid circuit with FDTD (Finite-Difference Time-Domain) algorithm, obtain the distribution of the electromagnetic field of the circuits at different moments, and the simulation result of FDTD and commercial software are highly consistent. As FDTD is a full-wave simulation, the calculation results are more accurate than those traditional circuit simulations, and the field value and distribution of electromagnetic field responding to high-frequent signal can be attained directly, which has important significance for researching the problems about electromagnetic compatibility and so on.
