A fast calculation tool for state-dependent capacitance of power distribution network is proposed. The proposed method achieves linear time-complexity, which can be more than four orders magnitude faster than a conventional SPICE-based capacitance calculation. Large circuits that have been unanalyzable with the conventional method become analyzable for more comprehensive exploration of capacita...

In this paper, using the tight-binding model, we extend the real-space renormalization group method to time-dependent Hamiltonians. We drive the time-dependent recursion relations for the renormalized tight-binding Hamiltonian by decimating selective sites of lattice iteratively. The formalism is then used for the calculation of the local density of electronic states for a one dimensional quant...

Conducted biomineralogical studies indicate piezoelectric properties of apatite, which is one of the major components of bone. This publication presents hypothetical correlations between piezoelectric properties of bone apatite and the accompanying electromagnetic phenomena in bones and their environment. It notes the correlations between electrical properties of bones and changes in the electr...

Abstract We propose a metasurface antenna capable of real-time holographic beam steering. An array reconfigurable dipoles can generate on-demand far-field patterns radiation through the specific encoding meta-atomic states i.e., configuration each dipole. Suitable for generation desired be identified using iteration, but this is very slow and needs to done pattern. Here, we present deep-learnin...

Paper analyzes a sparking phenomena that were observed on power transformers during their first few energizing. Sparks occurred the flange between tank cover and side, in spite of fact jumper (copper link) was used. The phenomenon from different manufacturers, with various transformer ratings, three or five limb core. proposes simple electromagnetic model for analyzing phenomena. Three-phase is...

This paper presents a Scott transformer model to be applied in electromagnetic transients (EMT) programs, particularly the absence of detailed for performing real-time simulations (RTS). Regarding transformer, common topology converting three-phase network into two single-phase networks, EMT programs is essential simulate large-scale electric railway systems. A code-based has been developed RTS...

Extraordinary transmission through a small aperture is of great interest. However, it faces a limitation that most of approaches can not realize the tunable transmission property, which is not benefit for the miniaturization of the microwave system. Here, we demonstrate a magnetically tunable broadband transmission through a small aperture. By placing two ferrite rods symmetrically on both side...

The present contribution is concern with an exact framebased expansion of planar initial time-harmonic electromagnetic fields. The propagating field is described as a discrete superposition of tilted and shifted electromagnetic beam waveobjects over the frame spatial-spectral lattice. Explicit asymptotic expressions for the electromagnetic Gaussian beam propagators are obtained for the commonly...
