    Abstract: We make use of the well-known integral representation of Bessel function in order to derive higher-order rotational electromagnetic waves. For this purpose, we employ the simplest weighting function in carrying out an azimuthal averaging of an E-parallel-H wave. To our surprise, the resulting wave turns out to describe interactions between two co-r... Show More

    Abstract: In this study, by using some tools available in optical observatory of Neyshabur University, consider some astronomy objects in the northern hemisphere (according the climate Neyshabur city). Then we analyze images (that taken by special filter) with some analyzer software and describe theirs component properties. Finally we compare some constellat... Show More
  • Radiation from Materials with Negative Dielectric Constant

    DOI: 10.11648/j.wjap.20160102.13
    Abstract: We consider the generation of diffusive radiation by a charged particle passing through a random stack of plates in the infrared region. The main mechanism causing radiation is multiple scattering of electromagnetic field that is more effective in a medium with near zero average dielectric permittivity. To enhance the radiation intensity one needs ... Show More
  • Calculation of Scattering Magnetic Fields, Arising at Current Flow Around Defects, as Applied to Electromagnetic Non-destructive Testing

    DOI: 10.11648/j.wjap.20160102.14
    Abstract: The aim of the electromagnetic non-destructive testing is the determination of structural defects in conductive materials by excitation of eddy-currents using an external alternating magnetic field and measuring a secondary field produced by these currents. For a reliable control of defects in a conductor it is necessary to find out how a certain f... Show More
  • Quantum Mechanical Potential Step Functions, Barriers, Wells and the Tunneling Effect

    Abstract: In this paper, use is made of the tools of analytical mechanics and the concept of operators to obtain the time-independent and time-dependent Schrodinger wave equations for quantum mechanical systems. Derivations are embarked upon of expressions for reflection and transmission coefficients for a particle of mass m as well as of energy E moving und... Show More
  • Quantum Phase Transition: Intra and Inter-Band Interaction on D- Wave Superconductivity

    DOI: 10.11648/j.wjap.20160102.16
    Abstract: There are compounds whose structures support superconductivity at high temperatures. They have intra and inter-band interactions which occur within their bands. However there has been no hybrid Hamiltonian developed so far for a lattice structure that can support conduction by both D-waves and other waves on the same Fermi surface. These waves inte...
