- Fourier transform infrared (FTIR) reflectivity and transmission spectroscopy in a wide temperature range (10-900 K), occasionally complemented by the time-domain terahertz transmission (TDTT) technique.
- Quantitative analysis of the vibrational spectra, lattice dynamics and dielectric dispersion. Special attention is paid to the structural phase transitions and soft mode dynamics.
- The research is focused on ferroelectric, antiferroelectric, incipient ferroelectric materials and microwave dielectrics. Coworking includes the study of the bound water dynamics and other polar matters.
- Effective dielectric response of inhomogeneous media. Specification of the grain boundaries role in the polycrystalline materials and mechanical stress in thin films.
