Bandwidth Enhancement for Half Mode Substrate Integrated Wave guide Antenna using Defected Ground Structures [PDF]
International Journal of Electronics and Telecommunications, 2023 The SIW antenna suffers from the narrow bandwidth for a single cavity and single resonant. Defected ground structure (DGS) with a dual cavity was the solution to solve narrow bandwidth by resulting in hybrid resonance.

Identifying the ground state structures of point defects in solids
npj Computational Materials, 2023 AbstractPoint defects are a universal feature of crystals. Their identification is addressed by combining experimental measurements with theoretical models. The standard modelling approach is, however, prone to missing the ground state atomic configurations associated with energy-lowering reconstructions from the idealised crystallographic environment.
