Introduction to the May 2025 Issue

Our May issue contains eighteen technical articles spanning magnetic resonance imaging (MRI) induced heating, implantable medical devices, human skin modelling in the microwave region, energy harvesting for electric vehicles, fully integrated THz radar circuitry implemented in silicon germanium, millimeter-wave indoor communications modelling, synthetic aperture radar imaging techniques, photonic-based multiple-input–multiple-output (MIMO) radar, a MIMO emulator, rectifiers for wireless power transfer, microwave switches, amplifiers, power combiners, and optimization techniques. We close with a general article on analyzing arbitrarily shaped waveguide discontinuities. We would also like to bring your attention to a new special issue we are targeting for release in early 2026 on Microwaves in Medicine and Biology. You will find the call for papers at the end of our Table of Contents for this May issue.
