Torque ripple reduction in homopolar poly-phase transverse flux machine
The Journal of Engineering, 2019 The problem of high ripple in output torque is inherent to switched reluctance and permanent magnet machines compared to conventional machines. Torque ripple is undesirable as it leads to increased audible noise, speed ripple, and fatigue.

Investigation of defect cavities formed in three-dimensional woodpile photonic crystals [PDF]
, 2015 We report the optimisation of optical properties of single defects in three-dimensional (3D) face-centred-cubic (FCC) woodpile photonic crystal (PC) cavities by using plane-wave expansion (PWE) and finite-difference time-domain (FDTD) methods.

Streamer and surface charge dynamics in non-uniform air gaps with a dielectric barrier
IEEE transactions on dielectrics and electrical insulation, 2019 Streamer behaviour near dielectric surfaces is an important characteristic of air-solid electrical insulation systems. Accurate predictions are important for dielectric design, but dynamic aspects such as surface charging during streamer propagation are ...
