Novel hybrid-polarized vector beams with radial and azimuthal polarization states in arbitrary fan-sectors are generated and studied for manipulating surface plasmon polaritons (SPPs). The method has high energy conversion efficiency based on an interferometric arrangement with a Dammann vortex phase grating. The polarization states of generated beams are measured by a linear polarizer and show...

We construct strong solutions for a nonlinear wave equation for a thin vibrating plate described by nonlinear elastodynamics. For sufficiently small thickness we obtain existence of strong solutions for large times under appropriate scaling of the initial values such that the limit system as h → 0 is either the nonlinear von Kármán plate equation or the linear fourth order Germain-Lagrange equa...

Background: The purpose of this study was to determine the percentage depth dose (PDD) of PAGAT normoxic polymer gel dosimeter by electron beams using MRI technique for a standard clinically used Co-60 therapy unit and an electa linear accelerator. Materials and Methods: Using MRI, the formulation to give the maximum change in the transverse relaxation rate R2(1/T2) was determined to be 4.5% N,...

Future linear colliders may require a nonzero crossing angle between the two beams at the interaction point. This requirement in turn implies that the beams will pass through the strong interaction region (IR) solenoid with an angle, and thus that the component of the solenoidal field perpendicular to the beam trajectory is nonzero. The interaction of the beam and the solenoidal field in the pr...

The free vibrations of cantilever slender beams polymers, which are viscoelastic materials, theoretically described using the simple Euler–Bernoulli assumption. comparison between theory and experimental data collected for a thermoplastic elastomer, polyether block amide, shows very satisfactory results. Consequently, is used thoughtful analysis impact material parameters beam geometry on its v...
