Simulation with MoM

I would like to ask if is possible to simulate the presence of a wall behind a dipole (d=20cm) using the MoM. If yes how can i do that? Is the wall(bricks) a dielectric material?
Any code available that can do that???
I would appreciate if you can answer me

Regards

you can draw the wall as a brick,then define the dielectric constant of the brick

oh,you shall use the air embrace your dipole and the wall, that is important,because some student use the default material to define the material between the dipole and the wall

Hi!

In principle it's possible, but I'd use time domain code.
Wall is a dielectric material but also loosy (or complex permittivity in other words) and frequency dependent!
It's hard to estimate the parameters of the wall but I'm sure you can obtain measured data.

Cheers

Hi ththeodosis

You can do it by applying wires instead of wall
It?s making the calculation simple.

Hi there,
what u mean by saying applying wires? Instead of the wall use wires with the parameters of the wall?

Assuming the grid spacing is much less than a wavelength, a wire grid does a decent job of approximating a plane. The screen door of a microwave oven is a good physical example of this. Solving for the currents on a grid is 1D problem and is relatively easy to solve.

The hard part will be finding an impedance boundary condition for the wire the mimics the brick wall.
