Localization of Low-frequency Source Current Distributions
Electromagnetic (EM) noise field distributions measured externally around electrical and electronic equipment have been used for localization and identification of the noise sources inside the equipment. For high frequencies (more than hundreds of MHz), the EM sources at finite distances have been localized by applying the techniques such as MUSIC [1], SPM [2], and holographic imaging [3], to t...
متن کاملUnited Mechanisms for the Generation of Low- and High-Frequency Tropical Waves. Part I: Control Experiments with Moist Convective Adjustment
To examine several mechanisms for the generation of lowand high-frequency tropical waves, numerical experiments are conducted using an idealized nine-level R21 spectral model with the original scheme of moist convective adjustment (MCA). The model prescribes globally uniform, time-independent distributions of sea surface temperatures and insolation, thereby excluding stationary waves and extrat...
متن کاملNonlinear tube waves in permeable formations: Difference frequency generation
We extend earlier work on nonlinear tube wave propagation in permeable formations to study, analytically and numerically, the generation and propagation of a difference frequency, ∆ω = ω1 − ω2, due to an initial pulse consisting of carrier frequencies ω1 and ω2. Tube waves in permeable formations have very significant linear dispersion/attenuation, which is specifically addressed here. We find ...
متن کاملAlong-Slope Current Generation by Obliquely Incident Internal Waves
Numerical studies of internal wave reflection from sloping boundaries are presented. Previous work (Slinn and Riley, 1996, 1998a, 1998b, 1999) has restricted attention to internal waves that approach the bottom slope in a plane normal to the boundary (normal incidence). This work extends the scope of the three-dimensional time-dependent numerical experiments to examine internal waves that appro...
متن کاملDesign Modification of Rogowski Coil for Current Measurement in Low Frequency
The principle object of this paper is to offer a modified design of Rogowski coil based on its frequency response. The improvement of the integrator circuit for nullifying the phase difference between the waveforms of the measured-current and the corresponding terminal voltage is a further object of this investigation. This paper addresses an accurate, yet more efficient measuring and protect...
