B07: Beam & High-Frequency Methods (1)

Wednesday, August 20  08:00-09:20,  Room #19

Session Chairs: Timor Melamed, Stefano Maci

The session will address the theory and topical applications of the whole range of high-frequency methods with a special focus on beam methods. By using the wavelength as a small parameter, the methods should lead to simpler approximate solutions of electromagnetic problems, thus allowing a physical insight into the solution and numerically efficient simulations of problems hardly treatable with direct numerical methods- The beam part of the sessions will focus on EM and scalar beam propagation and scattering as well as on application of beam (phase-space) expansions. Further methods of interest include the geometrical optics (GO), the geometrical theory of diffraction (GTD), the uniform theory of diffraction (UTD), the physical optics (PO) and the physical theory of diffraction (PTD). Papers on solutions of canonical problems to be used as building blocks in the high-frequency solutions and on topical applications like electromagnetic radiation, scattering and propagation in structures involving engineered materials (metamaterials, metasurfaces, etc) are particularly welcome.
