Analysis for the propagation of plane harmonic thermoelastic waves in an infinite homogeneous orthotropic plate of finite thickness in the generalized theory of thermoelasticity with two thermal relaxation times is studied. The frequency equations corresponding to the extensional (symmetric) and flexural (antisymmetric) thermoelastic modes of vibration are obtained and discussed. Special cases ...

The influence of the medium on gravitational deflection light rays is widely discussed in literature for simplest non-trivial case: cold non-magnetized plasma. In this article, we generalize these studies to case an arbitrary transparent dispersive with a given refractive index. We calculate angle ray moving general spherically symmetric metric presence equation radius circular orbits also deri...

We study the possible expansion of electromagnetic field scattered by a strictly convex metallic nanoparticle with dispersive material parameters placed in homogeneous medium low-frequency regime as sum modes oscillating at complex frequencies (diverging infinity), known physics literature quasi-normal expansion. show that such an is valid static and we can approximate electric finite number mo...
