Lightning Electromagnetic Transient Modeling of Photovoltaic Systems

Journal of Physics: Conference Series
Abstract Photovoltaic power plants are commonly constructed in open and unobstructed areas, where they are exposed to a high risk of lightning strikes. As a key protective component that ensures the safe operation of PV cells, the bypass diode is highly susceptible to damage from lightning-induced surges, which may subsequently ...

Additively Manufactured Porous Ceramics as Tunable Dielectrics for Passive Temperature Sensing

Advanced Materials Technologies, EarlyView.
Porous ceramic lattices, 3D‐printed from a multicomponent oxide ink, are integrated with LC resonators for passive wireless temperature sensing. By tuning porosity, the dielectric properties and RF response are engineered to produce distinct resonant frequency shifts with temperature. The results establish a structure‐driven approach to customizing the
