Simulation of the reflection phenomenon of an Electromagnetic Wave using the Finite Difference Method in the Time Domain

This document shows the computational simulation of the refraction phenomenon of an electromagnetic wave in transverse magnetic mode using the Finite Difference Time Domain Method with an operating frequency of 2.4×10
⁹
Hz (microwave frequency) and making a comparison with an electromagnetic wave of 4.8×10
¹⁴
Hz (frequency of the visible spectrum). The present document intends to show, by means of graphs, the propagation of electromagnetic waves in physical phenomena that we know but that it is impossible to see with the naked eye.
