“…It is assumed that the objective vectors are arranged in such a way that F (1) represents the vector being the closest to Fc = p -1 kF (k) (i.e., the geometric center of {F (k) }k = 1,…,p). The design xF (1) = U * (F (1) ) is found in a conventional way, i.e., through direct optimization; however, to reduce the cost, FBO is used whenever possible [65]. Having xF (1) , the inverse sensitivity matrix J x (F (1) ) is estimated using the procedure outlined in Section II.C.…”

“…Design of contemporary high-frequency structures, including microwave components and devices, heavily relies on full-wave electromagnetic (EM) analysis tools [1], [2]. Despite the advancements in the development of computing software and hardware, the high cost of repetitive simulations incurred by parametric optimization [3] or uncertainty quantification [4], is still a major bottleneck of EM-based design procedures.…”

“…Surface plasmon polaritons (SPPs), which employ the surface electromagnetic waves in the metallic nanostructures, has remarkable capability to manipulate light at the subwavelength scale beyond the diffraction limit. The extraordinary feature could miniaturize the physical dimensions of photonic components and has been regarded as a promising candidate in ultracompact photonic devices [6]- [11]. By combining metal with high-index nanowire, hybrid plasmonic waveguides (HPWs) have attracted particular attention [12]- [20].…”

Low-Loss Light Guiding at the Subwavelength Scale in a Nanowire-Loaded Hybrid Bloch-Surface-Polariton Waveguide

We report the realization of strongly confined low-loss optical waveguiding at telecommunication wavelength by exploiting the hybridization of photonic modes guided by coupled dielectric mode and Bloch surface polaritons on the interface between one-dimensional photonic crystal and dielectric nanowire. Owing to the combined effects induced by the coupling between two types of guided modes, tight field localization in conjunction with significantly lower propagation loss can be achieved simultaneously. The characteristics of the hybrid modes are comprehensively numerically investigated through tuning key structural parameters of the coupled dielectric nanowire and its distance to the photonic crystal surface. The hybrid mode could effectively balance the compromise between the mode confinement and propagation loss for a wide geometrical parameter range. It reveals the hybrid mode is capable of enabling larger propagation distance (centimeter level) with subwavelength mode confinement, leading to a high figure of merit nearly one order of magnitude larger as compared to the conventional hybrid waves in dielectric-metal-based surface plasmon waveguides over the range of dimensions considered. The outstanding properties of the proposed guiding scheme could open up possibilities for a variety of highperformance intriguing nanophotonic components.

“…A variety of spoof SPP-based filters and wave splitters have been realized for SSPP communication systems [12][13][14][15]. On the other hand, surface plasmon waveguide based antenna designs, ultra wideband antennas and full-band waveguide differential phase shifters have been proposed recently for microwave applications [16][17][18][19][20][21][22][23][24][25]. In [20][21][22][23][24][25], the maximum bandwidth obtained is around 6-7 GHz with an average gain of <10 dBi.…”

This paper proposes a technique to enhance the bandwidth and gain of an endfire radiating open-ended waveguide using a thin slow-wave surface plasmon structure. Mounted in the E-plane of the stated waveguide, a thin corrugated slow-wave structure has been used in conjunction with a waveguide transition to generate an endfire electromagnetic beam. An efficient mode conversion from waveguide transition to the corrugate plate resulted in the improved performance of the design. An impedance bandwidth from 8 GHz to 18 GHz has been achieved along with a gain enhancement from 7 dBi to 14.8 dBi using the proposed hybrid design. Endfire radiations have been obtained with a beam width of less than 25° through the proposed hybrid design with an efficiency of about 96 percent.
