Hello everyone,
In the wave optics module, frequency domain, modal analysis, I need to modify the wave equation. The default wave equation is the following:
∇×∇×E - ε k0^2 E = 0
λ = -jβ - δz
E(x,y,z) = E0(x,y) e^-iKz z
I want to modify the first line of the equation to:
∇^2E - ε k0^2 E = 0
How is this possible? I tried to create a custum physics envirnment by using the classical PDEs from Mathematics tab. However, I couldn't figure out how to implmemnt the second and third lines of the equations because it only lets me make one equation.
The attached is a very basic model in which I've used Helmholtz equation from the PDEs but couldn't make any progress because of the aformentioned problem.
Thank you,
Behnam
