An Intelligent Reconfigurable Graphene–VO2 Hybrid Terahertz Bandpass Filter Architecture for Differential Biomolecular Sensing and Machine Learning–Driven Analyte Characterization

International Journal of Optics, Volume 2026, Issue 1, 2026.
A compact hybrid graphene–VO2 terahertz (THz) bandpass filter integrating reconfigurable operation, differential biosensing, and machine learning (ML)–based prediction is proposed and numerically investigated. The device consists of a symmetric dual‐stepped‐impedance resonator (SIR) fabricated on a quartz/silicon substrate, where graphene provides ...

Compact microstrip pseudo-interdigital stepped impedance bandpass filters with improved stopband performance

, 2009
In this paper we present design of a compact microstrip pseudo-interdigital stepped impedance bandpass filter with improved stopband performance. Stepped-impedance resonators are used to maximise the ratio between higher order and fundamental resonances.

Conformal Filtering Patch Antenna With Dual Independently Tunable Radiation Nulls

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
A conformal, compact, and flexible patch filtering antenna with independently tunable radiation nulls is presented. By etching open‐ended split‐ring resonator (SRR) slots and meandered slots on a conformal microstrip patch, two independently controllable radiation nulls are introduced to enhance band‐edge selectivity.

A Compact Wideband HTS Duplexer Using Dual‐Mode Resonators with Improved Isolation

International Journal of RF and Microwave Computer-Aided Engineering, Volume 2026, Issue 1, 2026.
A wideband high‐temperature superconducting (HTS) duplexer is designed and is characteristic of more than 50% fraction bandwidth in its two channels. The duplexer is composed of a linear half‐wavelength resonator and two channels. Each channel is composed of five dual‐mode resonators with the attenuated second harmonic.
