E-band filters based on substrate integrated waveguide octagonal cavities loaded by complementary split-ring resonators

E-band filters based on substrate integrated waveguide octagonal cavities loaded by complementary split-ring resonators
In this paper, substrate integrated waveguide (SIW) octagonal cavities in conjunction with octagonal complementary split-ring resonators (CSRRs) are used to propose compact narrow bandpass filters at E-band. Short circuited slots are employed as coplanar waveguide (CPW) to SIW transitions as well as matching elements between adjacent stages of filters.

Plasmonic Nano-Sensor Based on Metal-Dielectric-Metal Waveguide With the Octagonal Cavity Ring

Laser Physics, 2018
Abstract In this paper, a refractive index plasmonic sensor including a waveguide of metal–insulator–metal with side coupled octagonal cavity ring has been suggested. The sensory and transmission feature of the structure has been analyzed numerically using Finite Element Method numerical solution.
