Wideband Millimeter‐Wave Balun‐Diplexer Based on a Novel Coupled Marchand Architecture for Compact Footprint and Phased‐Array Integration

Microwave and Optical Technology Letters, Volume 67, Issue 11, November 2025.
ABSTRACT This letter presents the first reported wideband balun‐diplexer for mm‐wave applications, designed for shared‐aperture full‐duplex array systems. By integrating balun and diplexer functionalities in a single component, we enable per‐element self‐interference suppression, while also facilitating the interface between the balanced feed of the ...

Prediction of Electric Permittivity of Threads in Woven Fabric

AUTEX Research Journal, 2018
In the article, a new method for the estimation of electric permittivity of threads (filaments) was presented. The proposed recursive method is based on the results of computer simulation of 3D model of transmission stripline. This model contains a model

Notched stripline resonator

Electronics Letters, 1969
A new type of stripline resonator is introduced. This is a compact microstrip resonator separated by a pair of notches from the feeder line. The width of the resonator is equal to, or smaller than, the feeder line. The resonator is suitable for d.c. biasing for various applications.

Defected Ground Structure (DGS) Based MIMO Antenna Array With Decent Isolation Characteristics for Satellite Communications in Unified S‐Band (USB)

Radio Science, Volume 60, Issue 11, November 2025.
Abstract This research focuses on developing an efficient, high‐isolation Multi‐Input Multi‐Output (MIMO) antenna array for Mobile Satellite Services (MSS). A portion of the S‐band (2–4 GHz) ranging from 2 to 2.2 GHz, known as Unified S‐Band (USB), is utilized for MSS, particularly for Space‐to‐Earth communications.

Comparison of the folded stripline and stacked stripline concepts to the folded waveguide launcher

, 1993
Two new concepts are being developed as possible upgrades to the folded waveguide launcher. The folded stripline is a folded waveguide with an additional conductor positioned inside. The term stripline refers to the resemblance of the design to microwave

AGORA: Adaptive Generation of Orthogonal Rational Approximations for Frequency‐Response Data

International Journal of Circuit Theory and Applications, Volume 53, Issue 10, Page 5751-5759, October 2025.
This paper introduces the adaptive generation of orthogonal rational approximations (AGORA) method for rational function approximation of measured or simulated microwave network parameters. AGORA allows estimating the model order for a given error tolerance and does not require any initial estimates or adjustment of hyperparameters. ABSTRACT This paper

Electron Spin Resonance at the Single‐Molecule Scale

Angewandte Chemie International Edition, Volume 64, Issue 37, September 8, 2025.
This minireview provides an overview of the four electron‐spin‐resonance techniques with single‐molecule sensitivity, relying on either optically detected magnetic resonance or scanning‐probe microscopy. After introducing underlying common concepts, it reviews the working principles, experimental conditions and key achievements.

Nitrogen‐Vacancy Magnetometry of Edge Magnetism in WS2 Flakes

Advanced Functional Materials, Volume 35, Issue 38, September 18, 2025.
Using nitrogen‐vacancy magnetometry, the authors visualize room‐temperature stray magnetic fields localized at the edges of WS2 flakes. Their measurements reveal edge‐specific magnetization consistent with spin canting in antiferromagnetically coupled edge states.
