Bandwidth enhancement of an ultra‐wideband printed slot antenna with WLAN band‐notched function [PDF]

, 2013
In this article, a compact ultra-wideband (UWB) slot antenna with band-notched performance is presented. To increase the impedance bandwidth of an ordinary slot antenna, we use a pair of S-shaped slots in the ground plane that with this structure a new ...

A Cavity-Backed Slot Antenna on Timber [PDF]

, 2021
Cavity-backed slot antennas can be used to detect anomalies and measure the dielectric properties of lossy media such as timber at microwave frequencies. An enhanced antenna design with the feed plate directly behind the rectangular slot allows maximum E-

Space‐Time Coding Conformal Metasurfaces for Multifrequency Beam Steering and Shaping

Advanced Materials, EarlyView.
Space‐time coding conformal metasurfaces enable dynamic wave control on curved surfaces by combining programmable spatial patterns with temporal modulation. This study shows that a single conformal aperture can independently manipulate multiple frequency components, achieving multifunctional beam shaping and steering, with implications for ...

Slot antenna as a bound charge oscillator

Optics Express, 2012
We study the scattering properties of an optical slot antenna formed from a narrow rectangular hole in a metal film. We show that slot antennas can be modeled as bound charge oscillators mediating resonant light scattering. A simple closed-form expression for the scattering spectrum of a slot antenna is obtained that reveals the nature of a bound ...

A High‐Resolution THz‐PCF Sensing Framework: Precise Identification of Food Preservatives Through Refractive Index Analysis

Advanced Materials Interfaces, EarlyView.
As presented in the graphical abstract, it depicts an image of a terahertz photonic crystal fiber (THz‐PCF) sensor with a polygonal shape in the core, which is filled with an analyte, and air slots in the cladding. The THz waves will travel through the fiber, and due to increased light‐matter interaction in the sensing region, changes in refractive ...
