We theoretically propose and investigate the resonant wavelength-selective optical filters based on the subwavelength metallo-dielectric nanopatch cavities and the metal slot waveguides. Using the temporal coupled-mode theory and three-dimensional finite-difference time-domain simulations. we analyze the optical coupling efficiencies and filtering characteristics. which are optimized ... https://www.jmannino.com/special-deal-A-Magazine-Curated-By-Sacai-quick-pick/
