R(fGHz, theta)

Calculate Reflection coefficient on the air|mat interface

fGHz : frequency GHz theta : incidence angle referenced from interface normal

Ro,Rp : orthogonal and parallel Reflexion coefficient

eval(fGHz)

evaluate Mat at given frequencies

fGHznp.array()

frequency (GHz)

w = 2*np.pi*f*1e-9 eps0 = 8.854e-12

100 MHz = 0.1 GHz 10 MHz = 0.01 GHz

sigma/(w*eps0) = sigma/(2*pi*fGHz*1e9*eps0) sigma/(w*eps0) = sigma/(2*pi*fGHz*1e9*8.854e-12) sigma/(w*eps0) = sigma/(2*pi*fGHz*1e-3*8.854) sigma/(w*eps0) = 17.98 * sigma/fGHz
