We consider scattering of electromagnetic waves by a thin structure of 
high index of refraction. We first consider the Helmholtz equation, and
show that if the squared refractive index scales as $O(1/h)$ where
h is the thickness of the scatter, an approximate solution based on
perturbation analysis can be obtained which involves solving a 2D
integral equation for a 3D problem. We then discuss extensions to
Maxwells' equations in this context while accounting for material
jumps, and the calculation of resonant frequencies by this asymptotic
