The research is primarily focused on the following three subjects: (1) Metamaterials, (2) nanoplasmonics, (3) Random Lasers.

1. Metamaterials - engineered media comprising metallic and dielectric nanoparticles and nanostructures. They exhibit unique properties, which make them useful for a variety of unparalleled applications including imaging and lithography with super-high resolution, invisibility cloaks, nanolasers, next generation telecommunication and information systems and many more.
Current research topics:

  • Active metamaterials
  • Metamaterials with hyperbolic dispersion
  • Magnetic Metamaterials

2. Nanoplasmonics - The performance of metamaterials in many cases depends on surface plasmons (SPs) and surface plasmon polaritons (SPPs). However, unfortunately, many applications of surface plasmons and surface plasmon polaritons suffer from damping caused by absorption in metals.
The major research topics of our group include:

  • Compensation of loss in SPs and SPPs by optical gain in dielectric medium
  • Stimulated emission of SPs and SPPs
  • Reduction of SP and SPP loss without gain
  • Alternative (non-metallic) plasmonic materials
  • Electron-plasmon interations
  • Non-Linear plasmonic phenomenon
  • Control of Emissions with metamaterials and plasmonics

(3) Random lasers – simplest sources of stimulated emission without cavity, in which the feedback is provided by scattering.
Current research topics:

  • Instability of random laser emission
  • Surface plasmon random laser
