This work presents a voltage mode scheme of full-wave precision rectifier circuit using an analog building block differential current conveyor transconductance amplifier (DVCCTA) including five NMOS transistors. The proposed design is essentially suited for low and high-frequency input signals. operation the depends upon region output waveform presented can be made electronically tunable by con...

Current algorithms for imaging seismic reflection data can be subdivided into two classes: Kirchhoff (generalized Radon transform) and wave-equation (double-square-root and reverse-time) migration. Kirchhoff type methods rely on asymptotic and ray-geometrical considerations. Wave-equation imaging algorithms (one-way or twoway) appear to be more robust in the case of complicated velocity models ...

A conformal cubical transformation-based metamaterial invisibility cloak is presented and verified, in the near and the far field, by a rigorous full-wave numerical technique based on a higher-order, large-domain finite element method, employing large anisotropic, continuously inhomogeneous generalized hexahedral finite elements, with no need for discretization of the permittivity and permeabil...

An integral equation reformulation of the Maxwell transmission problem is presented. The uses techniques such as tuning free parameters and augmentation close-to-rank-deficient operators. It designed for eddy current regime works both surfaces genus 0 1. Well-conditioned systems field representations are obtained despite being ill-conditioned 1 due to presence Neumann eigenfields. Furthermore, ...
