Abstract :
This paper presents a novel finite-difference time-domain (FDTD) method to calculate the resonant frequencies of cavity structures. The FDTD formulation, based on the wave equation, employs approximation techniques. The proposed algorithm takes a much shorter time than the standard FDTD method. The theory is verified by comparison with the analytic result.
