Challenges and Perspectives of Nanoelectromagnetics in the THz Range

Current trends in nanoelectromagnetics - a new field of research synthesizing classical radio physics and electrodynamics with quantum theory of solids, physical kinetics, quantum chemistry, computational mathematics - are analyzed with the focus on applications in the terahertz frequency range. The analysis is exemplified by the discussion of the THz response peculiarities of carbon nanostructures and composite materials with nanocarbon fillers. Some electromagnetic applications of nancaerbons are discussed, such as nanoantennas, amplifiers and generators of terahertz radiation, THz range functional materials for radar absorbing and reflective coatings.
