Code 12.4: Emissivity of a Periodic Sinusoidal Surface

Code Name: Emissivity_I2EM_Periodic.m

Description: Code computes emissivity for a random surface superimposed on a periodic sinusoidal surface.

Input Variables:

ε = ε^' - jε^'':	Dielectric constant of the surface (unitless)
Θ₀:	Incidence angle (degrees)
ɸ₀:	Look angle (degrees)—see Fig. 12-11
f:	Frequency (GHz)
s:	rms height (m)
l:	correlation length (m)
Λ:	Spatial period of periodic surface (m)
A:	Amplitude of periodic surface (m)

Output Products:

e^h(Θ₀, ɸ₀):	h-polarized emissivity (unitless)
e^v(Θ₀, ɸ₀):	v-polarized emissivity (unitless)
