A simple transformation of improved WLAN band pass to low pass filter using defected ground structure (DGS), defected microstrip structure (DMS) and multilayer-technique

Journal of Microwaves, Optoelectronics and Electromagnetic Applications
A novel transformation of band pass- to low pass filter is introduced in this paper. First a compact microstrip band pass filter designed, optimized and realized by combining a simple multilayer method with magnetically coupled microstrip U-shaped DGS ...

A 2.5 mW D‐Band Broadband Simultaneous Noise‐ and Input‐Matched InP LNA

Electronics Letters, Volume 62, Issue 1, January/December 2026.
This work presents a D‐band, ultra‐low‐power, broadband two‐stage low‐noise amplifier (LNA) implemented in a 250‐nm InP DHBT process. Using a simultaneous noise and input matching technique with a gain‐boosted feedback network, the LNA achieves 6.2 dB noise figure and 27 dB gain from 130 to 155 GHz while consuming only 2.5 mW.

Optimized absorbing boundary conditions for the analysis of planar circuits using the finite difference time domain method [PDF]

, 1993
It is shown that the description of absorbing boundary condition algorithms (ABCs) in terms of single incident plane waves does not provide sufficient information for choosing the best ABC for planar waveguide termination.

GPR Antenna Modelling Based on DML Exploiting Cosine Similarity Metric

IET Microwaves, Antennas &Propagation, Volume 20, Issue 1, January/December 2026.
The proposed SNN‐KNN‐GPR framework. ABSTRACT Traditional full‐wave electromagnetic simulation software, such as HFSS or CST, requires substantial computational resources and time consumption, as does the construction of surrogate models when acquiring new samples. To overcome this data efficiency challenge, we propose a Data Augmentation (DA) modelling

Graphene–Polyimide Flexible Electronic Platform Enabling Ultra‐Broadband High‐Gain THz MIMO Systems

Advances in Materials Science and Engineering, Volume 2026, Issue 1, 2026.
The integration of two‐dimensional (2D) materials with flexible substrates is pivotal for advancing next‐generation terahertz (THz) and sixth‐generation (6G) wearable electronics. However, a significant challenge remains in preserving the exceptional electronic properties of 2D materials such as graphene on low‐loss, mechanically robust dielectrics at ...

Circuit‐Theoretic Modeling and Simulation Study of Near‐Field MIMO Arrays of Dipole Antennas

Active and Passive Electronic Components, Volume 2026, Issue 1, 2026.
Near‐field mutual coupling among closely spaced antennas limits the deployment of wireless MIMO interconnects in chip‐to‐chip communication. This paper presents a circuit‐theoretic modeling and simulation study of near‐field MIMO (NFMIMO) systems using 1 × 1 and 2 × 2 dipole arrays.
