We propose to use double negative (DNG) metamaterial slabs to build effective super-absorbers and perfect nanodetectors for single divergent sources. We demonstrate by numerical simulations that an absorbing nanoparticle properly placed inside a DNG slab back-covered with a perfect electric conductor or perfect magnetic conductor mirror can absorb up to 100% radiation energy of a single dipole ...

The accurate and fast computation of the per unit length (pul) internal impedance of rectangular conductors is required in electromagnetic analysis of various engineering and scientific problems where high current frequencies are involved [1, 2]. This pul internal impedance of a rectangular conductor can also be used in more complicated conductor structures where the shape of the conductor is a...

A bend in a single-conductor line is primary cause of radiation associated with the antenna mode; conversely, fed back, resulting attenuation and distortion current waveform. Despite being fundamental phenomenon, its dynamics have not been sufficiently characterized. Therefore, this study presents transmission-line model for bent wire structures comprising multiple straight elements by using lo...

ONIOM calculation is carried out to estimate the acidity of five aliphatic alcohols before and after adsorbing on the tip of (8,0) single-walled carbon nanotube. The ONIOM method is performed using a combination of density functional theory and AM1 semiemperical method for alcohols and their corresponding conjugated bases. Deprotonation Gibbs free energies of alcohols are calculated and compare...

This paper presents an algorithm for the evaluation of currents and voltages along a multi-conductor transmission line having non-linear impedances due to presence ferromagnetic conductors; we assume that these are function current carried by relevant conductor so equivalent circuit modelling is has be solved means iterative procedure. The present can considered as generalization our previous w...

According to the galloping mechanism of iced conductors, the aerodynamic simulations were performed based on actual wind tunnel tests. Aeroelastic models of single and bundled conductors with a typical ice-coating section forms (crescent section) were set up. The simulation results were in good ag...

Solid-solid phase interconversion was observed in an organic conductor based on a hydrogen-bonded (H-bonded) TTF (tetrathiafulvalene) molecular unit, in which the π-stacked molecular arrangement and physical properties were dynamically changed with unexpected transformation of the H-bond unit between the planar and bent forms.

Polyethylene’s application for insulating is highly advanced but due to thermoplastic properties, its application confronts constraints such as the limited 70°C temperature of the conductor. Polyethylene thermosetting procedure in which molecules are knotted and a 3D-molecular-network formed is developed to conquer the mentioned problem and to raise the applicable temperature of the i...
