Advanced Engineering Materials, Volume 27, Issue 15, August 2025.This study explores aerosol jet‐printed (AJP) surface roughness, its effects on the performance of microwave electronics, and its process contributors. First, an electromagnetic model is vetted for AJP's unique roughness signature. Simulations are built which show process‐induced roughness is as significant as conductor resistivity in driving microwave

Mechanical Tuning of Air‐Filled Substrate Integrated Waveguide Cavities by Employing Dielectric Rods
Microwave and Optical Technology Letters, Volume 67, Issue 8, August 2025.ABSTRACT This study presents a simple method to obtain tunable cavity resonators in air‐filled substrate integrated waveguide (AFSIW) technology. It is based on the insertion of a dielectric rod from an opening placed on a side of the SIW cavity, whose resonance frequency is varied by changing the penetration depth of the rod. To avoid power leakage, a
