Abstract
The two main themes of the work have been the analytical and numerical study of resistive sheets in various configurations, and the low frequency scattering from a number of different types of particles. In large measure the resistive sheet work is approaching a natural conclusion and our understanding of the scattering properties of sheets is now almost sufficient for the design of low cross section shapes incorporating them. For a resistive strip or ribbon it was earlier shown that the bistatic scattered field can be expressed in terms of the current induced in the corresponding half plane, and the resulting (uniform) high frequency asymptotic expression gives accurate results even for strip widths which are a small fraction of a wavelength. An efficient procedure for computing the half plane current for any (complex) resistivity has now been developed. (Author)
