Convergence analysis of Left-Right splitting surface scattering method
Paul E Parbone, Mark Spivack, Orsola Rath Spivack
We study the convergence of the Left-Right splitting method (equivalent in key respects to the Method of Multiple Ordered Interactions and Forward-Backward method) for wave scatter…

Propagation in rough waveguides: Forward and inverse problems
Mark Spivack, Orsola Rath Spivack
We discuss here the direct and inverse problems for wave propagation in a waveguide with rough internal surface and arbitrary mean shape. The high degree of multiple scattering ins…

Random scattering by rough surfaces with spatially varying impedance
N. S. Basra, M. Spivack, O. Rath Spivack
A method is given for evaluating electromagnetic scattering by an irregular surface with spatially-varying impedance. This uses an operator expansion with respect to impedance vari…
