2D EM Wave FDTD Simulator (Dielectrics & Conductors)…

What is the 2D EM Wave FDTD Simulator?

The 2D EM Wave FDTD Simulator is a computational model that solves Maxwell's curl equations for electromagnetic waves in two dimensions. It uses the Finite-Difference Time-Domain (FDTD) method to simulate wave propagation through various media, including dielectrics and conductors.

By adjusting parameters such as frequency, amplitude, and material properties, users can observe how electromagnetic waves interact with different materials, providing a deeper understanding of wave behavior in complex environments.

How Does the FDTD Method Work?

The Finite-Difference Time-Domain (FDTD) method is a numerical technique for solving Maxwell's equations. In this simulator, it discretizes space and time into small cells and updates the electromagnetic field values at each cell based on the wave equation.

By iteratively applying these updates, the FDTD method simulates how waves propagate through different materials, allowing users to visualize phenomena such as refraction, reflection, and absorption.
