Hello,

Wire mesh or parallel bars are often used as a replacement for solid
reflectors.

Is there any practical formula, computer program or graph for
calculating the (plane wave) reflectivity/reflection coefficient of
wire mesh (for example chicken mesh)?

I am thinking of a formula where you have to enter cell/grid size, wire
thickness and frequency.

With kind regards,

If the cell dimension of the grid is 1/20 wl the grid is considered to be
effective as a continuous reflective plane. The same dimension of spacing
between parallel wires is also effective as a continuous reflector for EM waves
whose polarization is parallel with the wires.
