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 ...

Monolithic Terahertz Topological Mach‐Zehnder Interferometer

Advanced Materials, Volume 37, Issue 37, September 18, 2025.
A monolithic topological Mach‐Zehnder interferometer (MZI) is presented, integrating the splitter, combiner, and waveguide arms on a single chip. The interferometric fringes exhibiting high on‐off contrast with extinction ratios over 20 dB are achieved by utilizing tailored unit cells that facilitate interface‐dependent out‐of‐plane radiation losses ...

Design Procedure for Interdigital Waveguide Bandpass Filters Based on Flat Metallic Strips

Radio Science, Volume 60, Issue 3, March 2025.
Abstract In this work, we describe a new topology for interdigital bandpass filters implemented in waveguide technology. Compared to classical coaxial resonators, which are typically based on cylindrical metallic posts, the resonators that we propose are based on rectangular boxed cavities loaded with flat metallic strips of a finite thickness.

High-Contrast and Compact Integrated Wavelength Diplexer Based on Subwavelength Grating Anisotropic Metamaterial for 1550/2000 nm

IEEE Photonics Journal, 2021
A high-contrast and compact wavelength diplexer is presented for conventional 1550 nm and emerging 2000 nm based on a subwavelength-grating (SWG) coupler. The SWG silicon waveguide thoroughly blocks the light propagation around 1550 nm but fully supports

Three‐Way Equal Filtering Power Divider for Modern Communication Systems

Engineering Reports, Volume 7, Issue 1, January 2025.
A balanced three‐way filtering power divider that receives input power and delivers equal amount of output to its three output ports is developed and realized using microstrip technology. The design is well‐suited for modern communication systems due to its low insertion and return losses, sharp selectivity, and integrated filtering capability ...

Observation of a DC Bias Voltage Dependence of Second‐Order Harmonics in Temperature Compensated Surface Acoustic Wave Resonators

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This article reports the variation of second‐order harmonics (H2) with the DC bias voltage (DCBV) in surface acoustic wave resonators employing the SiO2/LiNbO3 structure. On the other hand, linear and third‐order nonlinear responses scarcely changed with DCBV. Possible origins of this phenomenon are also discussed.

Reflectionless Linearly/Circularly Polarised Patch Antenna Based on Loading Complementary Absorptive Branches

Electronics Letters, Volume 61, Issue 1, January/December 2025.
This letter proposes reflectionless linearly and circularly polarised patch antennas based on loading complementary absorptive branches. By establishing the equivalent circuit model of a conventional patch antenna, the complementary absorptive branch could be designed to dissipate the out‐of‐band energy through the grounded resistor, thereby achieving ...
