This paper deals with local buckling analysis of rectangular functionally graded material plates using finite strip method and based on classical plate theory. The modulus of elasticity of the plate is assumed to vary according to a power-law distribution in terms of the volume fractions of the constituents. The principle of minimum total potential energy is employed to obtain stiffness and sta...

We present a study of undoped AlGaN/GaN separate confinement heterostructures designed to operate as electron beam pumped ultraviolet lasers. discuss the effect spontaneous and piezoelectric polarization on carrier diffusion, comparing results cathodoluminescence with electronic simulations band structure Monte Carlo calculations trajectories. Carrier collection is significantly improved using ...

Dielectric multilayers with graded index treat the propagating waves impinging at different angles very differently, due to occurred total internal reflection. Such an ultra-sharp change in response can be exploited for filtering, manipulation, and tailoring of spatially distributed electromagnetic signals. Various utilities proposed filter such as power splitting, spatial dc isolation, beam sh...
