Characterization of CFRP Thermal Degradation by the Polarization-Frequency Reflectometry Method in Subterahertz Frequency Range

Numerical‐analytical method for determining the dielectric constant of 1D inhomogeneous plate in a waveguide

“…There exist various methods of electromagnetic‐wave non‐destructive testing, such as tomography, reflectometry, ellipsometry and so on. [8–13]. All of them require solving inverse diffraction problem that allows determining physical parameters of materials under study by the measured characteristics of the diffraction field.…”

Visualization of subsurface damage in woven carbon fiber-reinforced composites using polarization-sensitive terahertz imaging

“…However, the studies of THz imaging of carbon fiber-reinforced composites are quite limited, mainly due to the conductivity of carbon T fibers, which hinders the penetration of THz radiation at depth. Thus far, to our knowledge, THz imaging has mainly been applied to detect the damage on the surface of unidirectional carbon fiber-reinforced composites [12,13]. Although carbon fibers hinder the THz penetration, the interaction between the THz polarization and carbon fiber orientation can be utilized to extract detailed information which cannot be obtained by other NDE techniques.…”

Yevgeny Mitrofanovich Kuleshov, 1922–2016 – His contribution to early sub-millimeter wave quasioptics

“…In 2013, when his former student and the then head of this department died at the age of 65, Kuleshov had the courage and strength to take responsibility of an important research project of the European Union FP-7 Program. The project was dealing with HDB technology applied to the testing of Carbon-Fiber-Reinforced-Plastic materials used in the Airbus industry; see [14,16,26]. In 2015, he received the Honorable Mention signed by the President of NASU, for the fruitful work and contributions to the radio physics and electronics.…”
