The purpose is to provide a convenient and reliable tool for testing and benchmarking of diffraction solvers with an up-to-date interface and a number of well-tested and calibrated solvers that cover a wide domain in the space of the problem parameters. Interface conventions will allow users to add their own solvers to the product's front-end. The software may be used for direct field calculation in the presence of a particular scatterer and for tests of new numerical methods that deal with diffraction problems.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.

Inside the Earth-ionosphere waveguide, the integral is evaluated by the stationary phase method, and the field is determined by characteristics of two normal modes. At the ground, the integral is brought to Fock's diffraction formula, which calculates the field in the regions of geometrical shadow and semi-shadow. The computational formulas make it possible to use algorithms and programs of the normal mode approach that were developed for long-range radio paths.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.

However, the problem of lidar data interpretation is not solved yet. It is necessary to take into consideration the multiple scattering (MS) when laser radiation propagates in optically dense aerosol formations. The paper discusses the problem of numerical simulations of the lidar returns that account for contributions from single and double scattering from dense aerosol formations. We have analyzed the lidar equation that was obtained in Samokhvalov (1979) for an inhomogeneous atmosphere with account of single and double scattering. It is shown in the paper that double scattering \"forward-backward\" and \"backward-backward\" photon trajectories equally contribute to the backscattering intensity. This significantly simplifies the lidar equation, if the sounding pulse penetrates the cloud to the depth that is small compared with the diameter scattering volume at the cloud top.","PeriodicalId":344401,"journal":{"name":"Conference Proceedings 2000 International Conference on Mathematical Methods in Electromagnetic Theory (Cat.
