Circuit Modelling of Bandpass/Channel Filter with Microstrip Implementation

Indonesian Journal of Electrical Engineering and Informatics (IJEEI), 2020
This paper presents a step-by-step approach to the design of bandpass/channel filters. A 3-pole Chebyshev bandpass filter (BPF) with centre frequency of 2.6 GHz, fractional bandwidth of 3%, passband ripple of 0.04321 dB and return loss of 20 dB has been designed, implemented, and simulated.

Conformal and Multi‐Domain Radio Frequency Energy Harvesting System Based on Graphene for Internet of Things Applications

Interdisciplinary Materials, Volume 5, Issue 5, Page 879-888, September 2026.
This study details a multi‐domain graphene assembled film (GAF) based radio frequency (RF) energy harvesting system (GEHS) for Internet of Things (IoT) applications. The GEHS integrates a flexible dual‐band, dual‐polarization, dual‐beam antenna array based on GAF materials with a high‐efficiency rectifier.

Review on Processing Control Strategy for Electrochemical Additive Manufacturing

MetalMat, Volume 3, Issue 3, September 2026.
This review systematically summarizes recent progress in processing control strategies for ECAM, with three key regulation dimensions: current monitoring and closed‐loop control, temperature regulation, and electrolyte flow/nozzle design. The roles of these parameters in governing electrochemical kinetics, mass transport, deposition stability, and ...

Ambient‐Spray Ni–Cu(–O)/Ag Nanowire Transparent Heaters for High‐Temperature Heating and Far‐/Near‐Field EMI Suppression

Advanced Materials Interfaces, Volume 13, Issue 16, 18 August 2026.
A vacuum‐free, ambient‐spray Ni–Cu(–O)/Ag nanowire transparent‐heater platform is realized via conformal junction‐shell engineering and silica–hybrid overcoating, enabling robust high‐temperature heating together with GHz‐band far‐field EMI shielding and near‐field magnetic‐noise attenuation.
