چکیده
Discuss the scattering of a plane electromagnetic wave of angular frequency ω that is incident on a perfectly conducting sphere of radius a, which is at rest, when the wavelength obeys λ a (ka 1). Calculate the electromagnetic fields and the Poynting vector everywhere, and interpret these fields in both the near and far zones. Consider incident electromagnetic waves of both linear and circular polarization.

Short Communication On the scattering of point-generated electromagnetic waves by a perfectly conducting sphere, and related near-field inverse problems
A spherical electromagnetic wave is scattered by a bounded perfectly conducting obstacle. A generalization of the plane-wave optical theorem is established. For a spherical scatterer, low frequency results are obtained by approximating the known exact solution (separation of variables). In particular, a closed-form approximation of the scattered wavefield at the source of the incident spherical...
متن کاملPlane Wave Scattering by an Achiral Multilayered Sphere in an Infinitely Extended Chiral Host Medium
An analytic solution to the problem of plane wave scattering by an achiral multilayered sphere in a host chiral medium is obtained in this paper. By applying the radiation-to-scattering transform, the scattering problem can be considered as the specific radiation problems where the radiated source equivalent to the electromagnetic plane wave is located at infinity. The volumetric currents which...
متن کاملScattering of a spherical wave by a small sphere: an elementary solution.
Wave scattering by objects that are small compared to the wavelength (Rayleigh scattering) is usually studied for plane incident waves. However, knowledge of the full Green's function of the problem becomes necessary when the separation of scatterers from either an interface or each other is comparable to the scatterers' dimensions. Here, an elementary analytic solution is derived for diffracti...

L-band electromagnetic scattering from two-dimensional random rough sea surfaces are calculated by first- and second-order Small-Slope Approximation (SSA1, 2) methods. Both analytical and numerical computations are utilized to calculate incoherent normalized radar cross-section (NRCS) in mono- and bi-static cases. For evaluating inverse Fourier transform, inverse fast Fourier transform (IFFT) i...
متن کاملScattering of a Plane Electromagnetic Wave by a Small Conducting Cylinder
Discuss the scattering of a plane electromagnetic wave of angular frequency ω that is normally incident on a perfectly conducting cylinder of radius a (in vacuum) when the wavelength obeys λ a (ka 1). Comment also on the limit of large cylinders, ka 1, via the optical theorem. Extend the discussion to the case of small conducting elliptical cylinders, which have (small) flat strips as a limit. ...
