Research on:

• diffraction theory and interaction between the waves of different nature in the scatterers of the resonant size. Development of new methods of analytical regularization of the boundary-value problems of the theory of wave diffraction by the curved open-metal screens, locally non-homogeneous dielectric, plasma-like and chiral scatterers,

• investigation of the phenomena of interaction, transformation, conversion and bifurcation of the electromagnetic field modes in the complicated open electromagnetic structures, including the case of parameter located near a critical point of the dispersion equation,

• development of non-stationary non-linear dynamics of highly dispersive media,

• elaboration of new approaches to the development of the mm and sub-mm wavebands by using open resonators and waveguides in transmission lines, feeds, antenna systems, etc,

• development of the vacuum diffraction electronics, in particular, design and research on the mm and sub-mm waveband orotron sources (generators of diffraction radiation).
