Abstract
In this study, we describe characteristics of plasmonic filters based on stubs coupled perpendicularly to metal–insulator–metal waveguides. To achieve a desirable filter, a designing procedure is proposed based on impedance curves, which lead to responses with great accordance to those obtained by numeric techniques. We study the impact of stub lengths and distance between stubs on bandgap width and filter sharpening. In addition, we illustrate the existence of trade-off between filter dimensions and filter parameters, which lead to a discussion about advantages and disadvantages of these structures. Validation of analytic results is confirmed with the finite-difference time-domain method.
