IEEE India International Conference on Power Electronics, 2023 The shunt reactor is a key element in the Extra High Voltage (EHV) power system used for voltage regulation. The current drawn by the reactor is highly inductive; due to this feature, it presents constraints in current interruption by circuit breakers ...

From surface to volume plasmons in hyperbolic metamaterials: General existence conditions for bulk high-k waves in metal-dielectric and graphene-dielectric multilayers [PDF]
, 2014 We theoretically investigate general existence conditions for broadband bulk large-wavevector (high-k) propagating waves (such as volume plasmon polaritons in hyperbolic metamaterials) in subwavelength periodic multilayer structures.

Instantaneous modulations in time-varying complex optical potentials [PDF]
, 2016 We study the impact of a spatially homogeneous yet non-stationary dielectric permittivity on the dynamical and spectral properties of light. Our choice of potential is motivated by the interest in PT-symmetric systems as an extension of quantum mechanics.

Design and characterization of dielectric filled TM$_{110}$ microwave cavities for ultrafast electron microscopy [PDF]
, 2018 Microwave cavities oscillating in the TM$_{110}$ mode can be used as dynamic electron-optical elements inside an electron microscope. By filling the cavity with a dielectric material it becomes more compact and power efficient, facilitating the ...

Critical speeding-up near the monopole liquid-gas transition in magnetoelectric spin-ice
, 2013 Competing interactions in the so-called spin-ice compounds stabilize a frustrated ground-state with finite zero-point entropy and, interestingly, emergent magnetic monopole excitations.

Advanced Engineering Materials, EarlyView.High‐frequency (HF) welding of steel is limited by oxide inclusions that degrade weld quality. This study demonstrates, for the first time, the integration of a nonthermal Ar/H2 dielectric barrier discharge (DBD) plasma jet into HF welding. Local plasma treatment provides effective shielding and in‐situ oxide reduction, resulting in markedly fewer and ...
