The integral equation method for the H-polarization case looks<br />
sligh-tly nlore complicated. This is related to the fact that even<br />
for three-dimensional structures Maxiqell's equations l.oo?c simp1.e<br />

dien'ts of the conductivity arise:<br />
The pertinent equa.tion for H-polarization is (3.5) , i. e.<br />
with the usual splitting<br />

This equation corresponds to (3.41) for the E-polarization case.<br />
Green's function appropriate to (3.51) is defined as<br />
Physically G can be interpreted as the magnetic field due to an<br />

Multiply (3.51) by Gn and (3.52) by IIa, subtract and integrate over<br />
the whole space. Then
