This paper deals with the relatively new area of antenna design – the design of reconfigurable antennas. It explains what is the perspective of a reconfigurable antenna in a modern communication or sensing system. It also gives the overview of the most employed switch and tuning elements that enable antenna reconfiguration.

The residual resistivity ρ in metals caused by wedge disclination dipoles is studied in the framework of the Drude formula. It is shown that ρ ∼ L −p with p = 3 for biaxial and p = 2 for uniaxial dipoles (L is a size of dipole arm).

Present paper describes application of a computer intensive methodology to evaluate antenna susceptibility to random physical damage for a Dipole and a Bow-tie antenna. For each randomly generated damage pattern antenna parameters are simulated and statistical comparison is performed. Computer intensive statistical methods like the Bootstrap used for the post processing make fewer initial assum...

The need for directional antennas possessing high gain, wideband and circular polarization characteristics for different wireless applications has increased considerably. In this research paper, a slotted coaxial line fed cavity backed U-shaped cross dipole antenna is developed to achieve wide bandwidth and reconfigurable circular polarization. The cross dipole consists of two orthogonal U-shap...

Nano-antennas in functional plasmonic applications require high near-field optical power transmission. In this study, a model is developed to compute the near-field optical power transmission in the vicinity of a nano-antenna. To increase the near-field optical power transmission from a nano-antenna, a tightly focused beam of light is utilized to illuminate a metallic nano-antenna. The modeling...

-The surface, vertical displacements generated by a buried vertical dipole in an elastic half-space are given. The dipole is taken to have a ramp time-dependence and the results are in the form of integrals. These integrals are evaluated as functions of time for several epicentral distances.

A passive temperature-sensing antenna is presented in this paper, which consists of a meandering dipole, a bimetal strip and a back cavity. The meandering dipole is divided into two parts: the lower feeding part and the upper radiating part, which maintain electric contact during operation. As a sensing component, a bimetal strip coil offers a twisting force to rotate the lower feeding part of ...

─ This paper aims to present an effective electromagnetic (EM) modelling approach for circular bundle of single-walled carbon nanotubes (CBSWCNTs), based on the electrical conductivity, relative complex permittivity and linear distribution impedance by applying General Ohm’s law for this bundle. The equivalent single conductor material (ESCM) model for personification the CB-SWCNTs is presented...
