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...
