Resonant scattering of light by an open cylindrical cavity ruled on a highly conducting flat surface

Mostrar todas las versiones(2)

Electromagnetic scattering from a groove in the form of an open cylindrical cavity ruled on a planar, highly conducting flat surface, is analysed by means of an integral method based on Green's theorem and an impedance boundary condition. We consider that the groove has circular cross section a...
