Solution of the Maxwell's equations of the electromagnetic field in two dimensions by means of the finite difference method in the time domain (FDTD)

摘要

The solution of the Maxwell's equations by means of the nite timedomain di erence method (FDTD) is used to describe the propagationof the electromagnetic eld [1]. The method consists of transferring thedi erential equations of Maxwell to a discrete formulation, both spa-tially and temporally, that allows coding them and implementing them in an algorithm that provides a numerical solution, which provides a vi-sual overview of the physical behavior of electromagnetic waves for twodimensions. The applications of this method to solve di erent types ofproblems are diverse and o er adaptability for cases where the geome-try of the problem becomes more complex to analyze. So this techniqueprovides a tool capable of being applied to various disciplines of sciencewith which it is possible to study systems and quantify the phenomenaproduced by electromagnetic activity successfully.
