The fourth edition of the URSI Commission B School for Young Scientists is arranged on the occasion of the EMTS 2016. This one-day School is sponsored jointly by URSI Commission B and the EMTS 2016 Local Scientific Committee. The School offers a short, intensive course, where a series of lectures will be delivered by a leading scientist in the Commission B community. Young scientists are encouraged to learn the fundamentals and future directions in the area of electromagnetic theory from these lectures.

Mathematical problems arising in electromagnetics and acoustics always attracted attention of mathematicians. The traditional (physical) diffraction theory was created by Huygens (who formulated in 1660s the famous Huygens principle, according to which the wave propagation is caused by secondary sources), Fresnel (1818), Maxwell (1850s), Helmholtz (1859), Kirchhof (1882), and others. The modern level was achieved owing to the studies of Poincare (1892) and Sommerfeld (1896) when it became clear that the mathematical theory of diffraction is connected with certain nonselfadjoint boundary value problems (BVPs) for partial differential equations (PDEs) of mathematical physics in unbounded domains. Recently, this theory has been developed on a completely new mathematical level involving the theory of distributions (Colton, Kress, Kleinmann, Werner, Vineberg, Costabel, Stephan, and others). The corresponding aspects of the theory of pseudodifferential operators were developed by Kohn and Nirenberg (1965), Eskin (1973), Shubin (1978), Taylor (1981), Rempel and Schulze (1982), and Mazja (1970-80s) who considered the problems on manifolds with sharp edges. The typical BVPs associated with the wave diffraction are stated in domains that have noncompact boundaries stretching to infinity and contain inclusions large in comparison with a characteristic parameter of the problem (e.g. wavelength) or dimensions of the boundary inhomogeneities. Recent remarkable progress of computational resources has opened new possibilities for solving such problems based on the use of huge computer clusters employing parallel computations. These circumstances dictate the necessity of deeper studies of mathematical foundations of the electromagnetic field theory that would enable further development and creation of specifically oriented mathematical and numerical methods and techniques.
The course focuses on foundations of the mathematical theory of electromagnetic fields and waves and includes (i) review of differential operations and theorems of the vector analysis; (ii) basic notions of the electromagnetic theory, Maxwell’s equations; (iii) statements and analysis of the boundary value problems (BVPs) for Maxwell’s and Helmholtz equations in unbounded domains associated with the wave diffraction, plane waves, conditions at infinity; (iv) statements and analysis of the BVPs for Maxwell’s and Helmholtz equations associated with the wave propagation in guides, the mathematical nature of electromagnetic waves; (v) introduction to the integral equation method with application to the solution of the BVPs for the Helmholtz equation; and (vi) introduction to the theory of numerical solution of PDEs by finite difference, finite element, and Galerkin methods. The course offers a possibility of solving practical exercises and problems based on the considered basic theoretical items.
