摘要：

Wavenumber matching is crucial to proper designs of optical devices such as ring-bus waveguides or planar cavities. In particular, the range of in-plane wavenumbers needs to be adequately determined along the coupling direction. Often-times, numerically intensive search is necessary for its accurate determination for surface plasmon resonances in particular nanostructures. In this paper, a method based on contour integrals is employed in order to provide a rough idea on the coupling capability of participating optical components. An example is provided for a semi-infinite metal-dielectric periodic multilayer bounded by another semi-infinite medium.
