“…The coupling effects between the MIM WG and the resonator are crucially dependent on the aspect of the resonator. To date, several MIM WGs with diverse shapes of resonators have been investigated, such as circular/rectangularring shaped [17,18], triangular/bowtie-shaped [19,20], tooth-shaped [21,22], H-shaped [23], r-shaped [24], U-shaped [25], T-type [26], M-shaped [27], cross-shaped [28], elliptical-shaped, etc. The elliptical-shaped resonator merits simplicity and controllable resonance wavelengths (λ res ) [29].…”

We propose a susceptible multichannel plasmonic sensor for sensing refractive index (RI) and temperature media working in the visible to near-infrared range. The proposed structure’s resonator consists of an elliptical-shaped ring with two stubs at two sides and four metal nanorods side-coupled to two separated metal–insulator–metal waveguides. The optical responses of the structure, including transmittance spectra and magnetic and electric field distributions, are investigated using the finite element method (FEM) to obtain the optimal structural parameters. The designed structure supports five channels of Fano resonance modes because of the interaction between the narrowband mode of the elliptical-shaped ring resonator and the broadband mode of two separated MIM WGs. The maximum sensitivity values can reach 4500 nm/RIU for RI sensing, and the temperature sensitivity can get 1.00 nm/°C. The designed device exhibits excellent sensing performance and could pave the way for sensing devices with significantly higher sensitivity.

“…The use of dielectric materials allows for better impedance matching and broader operating frequency ranges [26][27][28] . The use of dielectric materials allows for miniaturization and integration of the antenna elements, making them suitable for applications where space is limited [29,30]. It also exhibits low cross-polarization levels compared to waveguideslot arrays [31][32][33], it means that the antenna can effectively transmit or receive signals with minimal interference from undesired polarizations [34,35].…”

This paper addresses the issue of constructing millimeter band antennas using dielectric waveguide structures. A new type of linear antenna, incorporating metal pins on the side walls of the grooved dielectric waveguide, is proposed for generating polarization perpendicular to the waveguide axis. However, these antennas suffer from the drawback of cross-polarized radiation in directions close to the waveguide axis. To overcome this limitation, a modified antenna design with transverse polarization is introduced, featuring a closed groove waveguide with a longitudinal slot in the top of wall. The paper provides a comparison between two types of dielectric waveguide antennas. First, waveguide antenna with grooves in the dielectric which resulting longitudinal polarization, and second, waveguide antenna with quarter-wavelength pins which resulting transverse polarization. Electrodynamic modeling data is provided to demonstrate the effectiveness of the proposed antennas for satellite, 5G antenna, and radar applications. Finally, antenna of quarter-wavelength pins is proposed with frequency of 39GHz, gain of 19.8dBi, width of radiation pattern of 3.2\(^{\circ}\) and side lobe level (SLL) of -13.3dB has been achieved.
