ABSTRACT

This paper gives a theoretical solution to the problem of determining the characteristics of a perfectly conducting spherical object when it is placed inside a quasi-optical transmission line in the form of a circular hollow dielectric waveguide (HDW) operating in the millimeter and submillimeter wave band. From the analytical expressions derived, the backscattering (radar) and extinction cross sections of that object are calculated through the excitation coefficient of dominant mode HE11 and geometrical parameters of the HDW. The comparison of the calculation results with the plane-wave scattering characteristics validates this technique as a good simulation for the scattering of a plane homogeneous electromagnetic wave by a spherical object in free space.
