Scattering From Chiral Cylinders of Arbitrary Cross-Sections Above a Ground Plane

Multiple scattering from gyrotropic bianisotropic cylinders of arbitrary cross sections using the modeling technique.

Based on the principle of the equivolumetric model, the multiple scattering from two-dimensional composite gyrotropic bianisotropic cylinders (GBC's) possessing a certain magnetic group of symmetry is studied by using the indirect modeling technique. At first, a mathematical formulation for the problem is carried out and its solution expressed in terms of a system of simultaneous linear equatio...

Electromagnetic Scattering from Parallel Chiral Cylinders of Circular Cross- Sections Using an Iterative Procedure

The electromagnetic scattering from a 2D chiral circular cylinders, illuminated by either a TEz or a TMz plane wave, is investigated using an iterative scattering procedure. The developed formulation and the implemented code simulate different types of cylinders, where the cylinders can be made of anisotropic chiral material with uniform or non-uniform chiral admittance distribution, homogeneou...

Scattering of Plane Waves on Finite Cylinders with Non-circular Cross-sections

An electromagnetic scattering model for multiple tree trunks above a tilted rough ground plane

An efficient and complete electromagnetic scattering model for multiple tree trunks above the ground is presented. The individual trunks are modeled by finite-length stratified cylinders, with an external corrugated bark layer. The ground is modeled by a dielectric half space underneath the cylinders, with a slightly rough interface. The spatial distribution of the cylinders is random over an e...

Inferring Neutrino Cross Sections Above 10 eV

Extremely high energy neutrinos propagating in the atmosphere or in the Earth can originate horizontal or upgoing air-showers, respectively. We calculate the acceptances (event rate/flux) for detecting both types of events by fluorescence detectors, both spacebased as with the EUSO and OWL proposals, and ground-based, as with Auger, HiRes and Telescope Array. We depict them as a function of the...
