Research of computational error behavior at the numerical simulation of curved electrodynamic systems
The paper presents an analysis of the approach to the numerical study of vacuum microwave electronic systems by finite-difference time-domain (FDTD) method. The results on approximating the boundary between two materials are presented. The influence of changes in the geometric shape of the resonator on the frequency obtained in the numerical experiment is analyzed. The sensitivity
of the boundary approximation methods to small changes in geometric parameters is investigated.
