Numerical study of the eigenmodes of selective microdevices with multivalued corrugations

In this paper we solve the homogeneous problem (with no incident field) of an almost closed cavity in a ground plane, where the shape of the cavity is described by a multivalued function. To solve this problem we find numerically the complex depths of the cavity for which the determinant of the scat...

We consider the excitation of the two lowest eigenmodes of each cavity and show that the complex resonant depths coincide with the anomalies present in the diffraction response of an infinite grating formed by this kind of cavities.
