Laser-Induced Damage in Optical Materials
isotropic lms. e angles should be measured in the appropriate incident medium
because this is purely a matter of geometry. Note, too, that as φ increases, the leakage for
a given cone apex angle falls.
13.10 Admittance Diagram
We introduced the idea of surface admittance, Y, in 1.3 and 1.4. Y is the surface admit-
tance and can be dened as C/B where B and C, the normalized total tangential electric
and magnetic elds, are those calculated at the appropriate plane or surface. Since it is
clear from the analysis in 1.4 that B and C depend only on what is beyond the appropri-
ate plane and not what is ...
