Abstract:
An electromagnetic wave analyzer for analyzing electromagnetic wave propagation by solving Maxwell's equations in both time and spatial domains, comprising:analysis command input means for producing a command to initiate a simulation after establishing initial conditions and parameters necessary therefor, the initial conditions and parameters including a temporal discretization interval &Dgr;t; and analyzing means, responsive to the command from said analysis command input means, for analyzing the behavior of an electromagnetic wave with an alternating direction implicit finite-difference time-domain method which refers to a state of the electromagnetic wave at a first time point to calculate a new state of the electromagnetic wave at a second time point being &Dgr;t after the first time point, the temporal discretization interval &Dgr;t being divided into first-half and second-half stages of computation, and different sets of electromagnetic field components being computed alternately in the first-half and second-half stages.
