Attenuation in corrugated rectangular waveguide

Electronics Letters, 1971
The attenuation characteristics of two corrugated rectangular waveguides propagating the dominant hybrid mode are shown to be significantly better over a wide bandwidth than those for a plain guide propagating the TE10 mode.

Study of Rectangular Waveguide Elements for Planar Wide-Angle Scanning Phased Array Antennas

, 2005
Rectangular waveguide elements in an infinite planar phased array are analysed with respect to wide-angle scanning. Three waveguide geometries are considered: two dual polarized square waveguides and one rectangular waveguide.

Synergic Magnetic–Dielectric Ni/Co‐Anchored Carbon Aerogels From Cellulose Nanofiber Scaffolds for Electromagnetic Shielding, Infrared Stealth, and Secure RFID Technologies

Small, EarlyView.
Ultralight Ni/Co‐anchored nanoporous carbon aerogels derived from TEMPO‐oxidized cellulose nanofibers integrate absorption‐dominated EMI shielding with infrared stealth. The hierarchical porous network provides dielectric/magnetic losses and suppresses thermal signatures.

High-Gain Waveguide-Fed Circularly Polarized Spidron Fractal Aperture Antenna

Applied Sciences, 2019
A high-gain rectangular waveguide-fed aperture antenna that uses a Spidron fractal structure to produce circular polarization is proposed. The antenna consists of a Spidron fractal aperture etched onto the ground plane of a dielectric substrate that is ...

Chiral Plasmonic Filtering in Silver Nanowires via Point‐Defect‐Induced Mode Conversion and Interference

Nanophotonics, Volume 15, Issue 21, 12 November 2026.
A single nanogroove milled into a silver nanowire is shown to function as an on‐chip chiral plasmonic filter. The point defect selectively converts and interferes with guided plasmonic modes, enabling handedness‐dependent transmission under ± 45° polarized excitation.
