Scattering of a Plane Electromagnetic Wave by a Small Conducting Cylinder
نویسندگان
چکیده
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. Relate the case of a small strip to that of a screen with a small slit using the electromagnetic version of Babinet’s principle.

Electromagnetic Scattering from a Perfect Electromagnetic Conductor Cylinder Buried in a Dielectric Half-space
An analytical solution is presented for the electromagnetic scattering from a perfect electromagnetic conducting circular cylinder, embedded in the dielectric half-space. The solution utilizes the spectral (plane wave) representations of the fields and accounts for all the multiple interactions between the buried circular cylinder and the dielectric interface separating the two half spaces.

The electromagnetic scattering problem of a short-pulse plane wave by a perfectly-conducting circular cylinder, buried in a dielectric half-space, is solved by means of a cylindrical-wave approach (CWA). The incident plane wave may have a rather general shape in the time domain. The technique is applicable for arbitrary polarization, for any cylinder size and burial depth, and it gives results ...
