We both theoretically and experimentally examine the behavior of the first- and the second-order rainbows produced by a normally illuminated glass rod, which has a nearly elliptical cross section, as it is rotated about its major axis. We decompose the measured rainbow angle, taken as a function of the rod's rotation angle, into a Fourier series and find that the rod's refractive index, average...

We measured the supernumerary spacing parameter of the first- and second-order rainbows of two glass rods, each having an approximately elliptical cross section, as a function of the rod's rotation angle. We attribute large fluctuations in the supernumerary spacing parameter to small local inhomogeneities in the rod's refractive index. The low-pass filtered first-order rainbow experimental data...

On the basis of a mathematical model, problem compression two elastic transversely isotropic half-spaces, one which contains shallow near-surface groove an elliptical section, is considered. The solution to obtained using Elliott representation for body in terms harmonic functions, classical potentials and reducing boundary value considering integro-differential equation with unknown domain int...

The dynamic behavior of a three-layer cylindrical structure normal elliptical cross-section with discrete polymer filler under internal non-stationary loading was investigated. A finite element model the created and calculations deflections stresses its bearing layers were performed using software calculation complex Fimap NX Nastran. values specified in absence presence reinforcement aggregate...

Utilizing boundary integral method (BIM), we investigate molecularspontaneous emission rate enhancement in the vicinity of plasmonic nanoparticles ofelliptical cross section. These types of nanoparticles can considerably enhance themolecule decay rate. The spontaneous emission rate can be modified by altering theaspect ratio of the elliptical nanoparticle, the background refractive index andnan...
