A 53–125 GHz chip to double‐ridge rectangular waveguide transition

Electronics Letters
A novel chip to double‐ridge rectangular waveguide transition, with an ultra‐broadband operation bandwidth exceeding three standard rectangular waveguide (WR) bands of WR15, WR12, and WR10 is demonstrated for the first time in this letter, to the best of

Monolithically Integrated III–V Heterostructure Photonic Crystal Lasers on Silicon‐on‐Insulator

Nanophotonics, Volume 15, Issue 19, 13 October 2026.
Our work demonstrates slow‐light‐enabled photonic crystal lasers monolithically integrated on SOI using selective lateral heteroepitaxy. The slow‐light photonic crystal waveguides provide enhanced light–matter interaction to enable the lasing operation with an estimated group index of 31.8. The results provide a pathway toward compact, energy‐efficient

Surface roughness impact of 3D Ti-alloy printed WR-10 waveguide and rectangular horn antenna at W-band (75-110 GHz)

Micro and Nano Systems Letters
To investigate the effect of the surface roughness of 3D-metal-printed sub-THz components, the WR-10 3-inch-long waveguide and 24 dBi rectangular horn antenna were 3D-metal-printed using a titanium alloy powder and a high-resolution 3D metal printer. The

Analysis of leaky-wave antenna based on partially-filled rectangular waveguide

Известия высших учебных заведений России: Радиоэлектроника, 2015
A leaky-wave antenna based on the partially-filled rectangular waveguide with transverse slots is investigated. Using tensor Green’s functions for antenna radiation analysis is suggested.

Eigenvalues of Rectangular Waveguide Using FEM with Hybrid Elements

, 2002
A finite element analysis using hybrid triangular-rectangular elements is developed to estimate eigenvalues of a rectangular waveguide. Use of rectangular vector-edge finite elements in the vicinity of the PEC boundary and triangular elements in the ...
