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.

MINIATURIZED MICROSTRIP PATCH ANTENNA WITH DEFECTED GROUND STRUCTURE [PDF]
Progress In Electromagnetics Research C, 2014 The aim of this work is to miniaturize a microstrip patch antenna resonating at 3 GHz. For this purpose, defected ground structure (DGS) has been employed to shift the resonance frequency of an initial microstrip antenna from 5.7 GHz to 3 GHz by disturbing the antenna's current distribution.

A Defected Ground Structure Based on Matryoshka Geometry
Journal of Microwaves, Optoelectronics and Electromagnetic Applications, 2022 Abstract A Defected Ground Structure, DGS, based on matryoshka geometry is described in this paper. The proposed DGS geometry is outlined and initial design equations are presented. Four prototypes, with resonant frequencies 2.17 GHz, 2.44 GHz, 2.99 GHz and 3.73 GHz, were designed, fabricated and characterized, observing a good agreement between ...
