Multi-physics design optimisation of a GaN-based integrated modular motor drive system

open access: yesThe Journal of Engineering, 2019
Here, a multi-physics approach is presented for the design optimisation of an integrated modular motor drive (IMMD). The system is composed of a modular permanent magnet synchronous motor (PMSM) and a GaN-based modular motor drive power stage.

Electromagnetic Modeling of Split-Ring Resonators [PDF]

open access: yes2006 European Microwave Conference, 2006
In this paper, we report our efforts to model split-ring resonators (SRRs) and their large arrays accurately and efficiently in a sophisticated simulation environment based on recent advances in the computational electromagnetics. The resulting linear system obtained from the simultaneous discretization of the geometry and Maxwell's equations is solved

A Polarimetric First-Order Model of Soil Moisture Effects on the DInSAR Coherence

open access: yesRemote Sensing, 2015
Changes in soil moisture between two radar acquisitions can impact the observed coherence in differential interferometry: both coherence magnitude |Υ| and phase Φ are affected. The influence on the latter potentially biases the estimation of deformations.
