Auger Parameter Analysis for TiN and AlN Thin Films via Combined In Situ XPS and HAXPES

Surface and Interface Analysis, Volume 58, Issue 6, Page 387-399, June 2026.
ABSTRACT Auger parameter analysis provides in‐depth information about electronic and chemical bonding properties of TiN and AlN thin films, which are relevant across a wide range of technologies. Meaningful interpretation and analysis of Auger parameter of these materials have been hindered due to, among other reasons, the absence of reliable ...

A MIMO Dielectric Resonator Antenna in single DRA Element with Reduce Mutual Coupling

, 2022
Abstract A multiple input multiple output (MIMO) dielectric resonator antenna (DRA) with reduced mutual coupling is presented in the paper. The antenna resonates at dual frequencies of 4.91GHz and 6.5GHz with a coupling of less than -35dB. Unlike other DRA MIMO antennas, the design proposed in this work implements a single DRA to cover both ...

Additive Manufacturing of Broadband Dielectric Resonator Antennas Using Graded Permittivity and Modal Analysis

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This study enhances the bandwidth of dielectric resonator antennas (DRAs) by introducing a linearly graded permittivity profile. Characteristic Mode Analysis reveals that this approach broadens the modal distribution and extends the dominant resonant mode bandwidth.

Wideband and Frequency‐Reconfigurable Loop Antenna for Sub‐6 GHz Applications

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
This work tackles the longstanding bandwidth limitation of loop antennas by introducing a compact, symmetrical design that integrates a microstrip balun and periodic varactor loading. Unlike existing methods that often compromise symmetry or beam control, the proposed structure achieves both wide impedance bandwidth and frequency reconfigurability ...
