This method occupies a particular place among the methods of solution of diffraction problems. ... A detailed discussion of the questions connected with the application of the integral equations to light scattering problems can be found in [ 24 , 401 , 464 ]. For solution of the integral equations one uses different methods: method of moments, Galerkin method, etc. 228 , 243 , 265 , 380 , 434 , 467 , 495 , 500 ]. ...

The absorption of MHD waves due to the cusp (or the slow) resonance is studied numerically and the obtained results are discussed with respect to a possible application to conditions that are typical for the solar corona. The considered configuration is composed of two homogeneous regions separated by an inhomogeneous slab through which all physical parameters of the medium change continuously according to an initially prescribed distribution. ...

Next: Example of Deconvolution: Up: Interactive Deconvolution with Error Previous: Introduction . ... To a first approximation, the experimental data are related to the original object , the intensity of the source at some high level of resolution, by an experimental transfer relation: where is the Point Spread Function. ... The choice of its diameter is of fundamental importance because it is closely related to the resolution limit of the reconstruction process. ...
