dc.description.abstract | In this report we describe the theory and some implementation issues of a finite difference code used at SACLANT Centre. In particular, we consider the modelling of attenuation and the excitation of a remote incident field by using Huygen's sources. A series of comparisons of finite difference results with analytical results is performed. The report concludes with a series of computations of scattering of a generalized plane wave from a buried cylinder where the transmitted portion of the generalized plane wave is evanescent. An example of time-reversed propagation of a scattered field is also given. | |
