Subwavelength plasmonic cavity resonator on a nanowire with periodic permittivity variation
An electromagnetic cavity resonator with deep subwavelength size is considered theoretically on plasmonic nanowires with periodically modulated permittivity. In this work, plasmonic nanowires are treated as ∈negative cylindrical waveguides (ENGCWs) in a certain band of frequency whose guided wavelength for a small radius waveguide is small compared to the free-space wavelength. The dispersion r...
متن کاملBroadband coaxial cavity resonator for complex permittivity measurements of liquids
A novel cavity perturbation technique using coaxial cavity ruonators for the measurement of complex permittivity of liquids is presented. The method employs two types of resonators (Resonator I and Resonator ll). Resonator l operates in the fre quency range 600 MHZ-7 CH2 and resonator ll operates in the frequency range 4 Gliz-14 CH2. The introduction of the capillary tube filled wit? the sampl...
متن کاملPlasmonic Adder/Subtractor Module Based on a Ring Resonator Filter
A four port network adder-subtractor module, for surface plasmon polariton (SPP) waves based on a ring resonator filter is proposed. The functionality of module is achieved by the phase difference manipulation of guided SPPs through different arms connected to the ring resonator. The module is designed using the concepts of a basic two-port device proposed in this paper. It is shown that two po...
متن کاملSubwavelength plasmonic lasing from a semiconductor nanodisk with silver nanopan cavity.
We report the experimental demonstration of an optically pumped silver-nanopan plasmonic laser with a subwavelength mode volume of 0.56(lambda/2n)(3). The lasing mode is clearly identified as a whispering-gallery plasmonic mode confined at the bottom of the silver nanopan from measurements of the spectrum, mode image, and polarization state, as well as agreement with numerical simulations. In a...
متن کاملGuided modes supported by plasmonic films with a periodic arrangement of subwavelength slits
We calculate the guided band diagram of a metallic film with a one-dimensional periodic arrangement of cut-through subwavelength slits. We find that this system supports two distinct types of guided modes propagating in a direction perpendicular to the slits when the metal obeys a plasmonic dispersion model. The first type is a well-known surface mode. The second type results from the presence ...
