Program
emirs.m
computes the TE and TM emissivities from Gaussian rough surface using the small
perturbation method (SPM).
- epol=emirs(ipol,theta,lambda,epsilon,lc,hh)
Input
- ipol: calculate TE
(ipol=1) or TM (ipol=2)emission
- theta: polar angles
(deg) from 0 to 90
- lambda: wavelength in
free space
- epsilon: relative
permittivity of lower medium
- lc: rough surface
correlation length in lambda
- hh: rough surface rms
height in lambda
Output
- epol: total emissivity
in TE or TM for each angle in theta
Examples
(a) ipol=1, theta=[0:2:90], lambda=1, epsilon=17+i2,
lc=1, hh=0, 0.1, 0.2, and 0.3:
(b) ipol=2, theta=[0:2:90], lambda=1, epsilon=17+i2,
lc=1, hh=0, 0.1, 0.2, and 0.3:
