Analytical Modeling of Resonant Cavities for Plasmonic-Slot-Waveguide Junctions
IEEE Photonics Journal, 2011 Transmittance of a straight junction between two plasmonic slot waveguides can be enhanced by either coupling a perpendicular stub to the input waveguide or inserting an intermediate slot section between the waveguides. We derive analytic expressions for
