Consider a 1 D space with discrete grid points represented by indices i = 1 , 2 , 3 , dots, N . The electric
Consider a D space with discrete grid points represented by indices dots, The electric field at each point is governed by the update equation:
where is the time index is the time step, and is the permittivity of the medium. The magnetic field is updated as:
where is the permeability of the medium.
Write a MATLAB script to simulate the propagation of an electromagnetic wave in a D space using the FDTD method. Assume a sinusoinal source function at the center of the domain at time
Parameters are as follows:
Number of grid points is
Spatial step is and and time step is "obviously" related to this value.
Frequency of the source is
Permittivty and Permeability is and respectively.
Simulate the wave propagation for time steps and visualize the electric field and at different plots.
Your code must include explanation for every key steps and parameters used.
