An exact analytical solution is obtained for the scattering of electromagnetic waves from a plane wave with arbitrary directions of propagation and polarization by an aggregate of interacting homogeneous uniaxial anisotropic spheres with parallel primary optical axes. The expansion coefficients of a plane wave with arbitrary directions of propagation and polarization, for both TM and TE modes, ...

in present work, we have calculated the electronic properties including density of states (dos) and electron density for gan, inn and in wurtzite phase for x=0.5. the study is based on density functional theory (dft) with full potential linearized augmented plane wave method (fp-lapw) by generalized gradient approximation (gga-pbesol) for calculating electronic properties. in this report we con...

Abundant research suggests that the study of lay theories helps to explain intergroup relations. Building on this work as well as ‘‘interactionist’’ theories for understanding social behaviour from developmental and social psychology, we propose an integrative social-developmental perspective examining how lay perceivers’ characteristics (e.g., age, race, psychological motivations) interact wit...

The plane wave expansion method for calculating magneto-photonic crystals (MPCs) is modified via complex Fourier factorization whose basic principles are briefly explained. The new approach is used to simulate the photonic band structure of a twodimensional MPC made as Bi:YIG rods arranged with square periodicity. The considerable improvement of the convergence properties is demonstrated for se...

On the basis of Maxwell's equations and a plane wave expansion method, photonic band structure is computed for 3D chalcogenide photonic crystal with diamond lattice. The geometrical influence on the photonic bandgap is studied for three dimensional chalcogenide photonic crystal of diamond lattice for both chalcogenide spheres in air and air spheres in chalcogenide background. The air spheres in...

We report instability structures and nonlinear phenomena that arise when unstable and stable nonlinear wave fields are coupled nonlinearly. This interaction is modelled with an integrable system of cubic nonlinear Schrödinger (NLS) equations and plane wave data. The linearized analysis is straightforward, and robust to non-integrable perturbations. The coupled nonlinear Schrödinger (CNLS) model...

We study the quantum mechanics of BMN operators with two scalar impurities and arbitrarily many traces, at one loop and all genus. We prove an operator identity which partially elucidates the structure of this quantum mechanics, provides some support for a conjectured formula for the free all genus two-point functions, and demonstrates that a single O(g2 2) contact term arises in the Hamiltonia...

We carefully analyze the supersymmetry algebra of closed strings and open strings in a plane wave. We use eight component chiral spinors, SO(8) Majorana-Weyl spinors, in lightcone gauge to provide a useful basis of string field theory calculation in the plane wave. We consider the two classes of half BPS D-branes, D±-branes, preserving 16 supersymmetries. We exhaustively provide the supersymmet...
