We demonstrate terahertz THz pulse propagation on a cylindrical aluminum plate, with low loss and negligible dispersion via transverse-electric type whispering gallery WG modes. We observe an apparent superluminal effect where the group velocity is greater than c, and explain this phenomenon by means of a plane-wave description of the WG modes. The propagation loss is dominated by the diffracti...

We derive a non-Markovian master equation for charged particle in magnetic field coupled to bath and study decoherence by analysing the temporal decay of off-diagonal elements reduced density matrix position basis. The coherent oscillations characterised cyclotron frequency get suppressed as result due coupling with environment. consider an Ohmic three distinct models high-frequency cutoff spec...

We propose and demonstrate self-aligned Double Injection Function Thin Film Transistor (DIF-TFT) architecture that mitigates short channel effects in 200 nm on non-scaled insulator (100 SiO 2 ). In this conceptual design, a combination of ohmic-like injection contact high injection-barrier metal...

We study the reduced dynamics of a spin (qubit) coupled to a spin-boson environment in the case of pure dephasing. We derive formal exact expressions which can be cast in terms of exact integro-differential master equations. We present results for a SB environment with ohmic dissipation at finite temperatures. For the special value of the ohmic damping strength K = 1/2 the reduced dynamics is f...

Ohmic heating technology is generally used for processing liquids and solid-liquid mixtures (or pumpable foods) in the food industry. In ohmic processing, the product is heated volumetrically by dissipation of electrical current through it. The main advantages of ohmic heating are the rapid processing and relatively uniform heating achieved. In this review, the application and potential of ohmi...

In this formulation, the objective function and operating constraints include the corona power-loss term. The objective function consists of three terms: cost of investment of new transmission lines, ohmic power loss of new and existing lines, and corona-power loss of new lines. This combination of terms results in a non-linear objective function. The non-linear programming or the non-convex op...

An electrochemistry model was developed to analyse the J-V characteristics of a Proton Exchange Membrane (PEM) water electrolyser for hydrogen production. The Butler-Volmer equation and water transport characteristics through electrolyte membrane were employed to simulate the electrode activation overpotential and membrane ohmic overpotential, respectively. The modeling results are found to agr...
