In this paper, a planar monopole antenna is introduced, also we added some new Nano fillers such as Fumed Silica and Aluminum Oxide to RT Duriod5880 and RO3003 to produce new Nano composite materials, then new Nano composite materials are used as a substrate of a ultra-wideband monopole antenna. Antenna characteristics are considered to illustrate that, by using these Nano composite materials, ...

A large manifold of nontrivial spin textures, including the stabilization of monopole-like fields, are generated by using a completely new and versatile approach based on the combination of superconductivity and magnetism. Robust, stable, and easily controllable complex spin structures are encoded, modified, and annihilated in a continuous magnetic thin film by defining a variety of magnetic st...

The electric dipole moment of a magnetic monopole with spin is studied in the N = 2 supersymmetric gauge theory. Dipole moments of electric charge distributions, as well as dipole moments due to magnetic currents, are calculated. The contribution of the charge distribution of the fermion to the gyroelectric ratio is expressed in terms of ζ(3).

We continue our study of the effect of light fermions on the charge degree of freedom of magnetic monopoles. Even though the gauge coupling is weak, the Fermi vacuum is strongly perturbed by its coupling to the charge degree of freedom of the monopole. To obtain a correct picture of the vacuum we concentrate on the lowest partial wave of the Fermi field about the monopole core. We find that thi...

We investigate in detail the problem of constructing magnetic monopole solutions within the finite-range electrodynamics (i.e., electrodynamics with non-zero photon mass, which is the simplest extension of the standard theory; it is fully compatible with the experiment). We first analyze the classical electrodynamics with the additional terms describing the photon mass and the magnetic charge; ...

The existence of magnetic charges has appeal from the theoretical point of view: it explains the quantization of the electric charge and symmetrize Maxwell’s equation. Therefore, from 1931, when the famous Dirac paper [1] was published, searches for magnetic monopoles were carried out at every new generation of accelerators, but all those attempts were futile. Now it is generally accepted that ...

The quantum mechanics of a spin 1 2 particle on a locally spatial constant curvature part of a (2 + 1)-spacetime in the presence of a constant magnetic field of a magnetic monopole has been investigated. It has been shown that these 2-dimensional Hamiltonians have the degeneracy group of SL(2, c), and para-supersymmetry of arbitrary order or shape invariance. Using this symmetry we have obtaine...

Certain nontopological magnetic monopoles, recently found by Lee and Weinberg, are reinterpreted as topological solitons of a non-Abelian gauged Higgs model. Our study makes the nature of the Lee-Weinberg monopoles more transparent, especially with regard to their singularity structure.

We determine the critical strength of the effective electric coupling for the onset of Bose condensation of stable magnetic monopoles and antimonopoles in SU(2) Yang-Mills thermodynamics. Two scenarios are considered: infinitely fast and infinitely slow downward approach of the critical temperature. Our results support the claim that the first lepton family and the weak interactions emerge from...

We study the continuum limit of the length spectrum of magnetic monopole structures found after various Abelian projections of pure gauge SU (2), including the maximally Abelian gauge. We comment on Gribov copies, and measurements of the string tension.
