Abstract: Imaging and analytic methods are the basis of the experimental part of material science and can be used for the detection and identification of substances and the determination of their physical, chemical, and structural properties. In the continuation of the research programme, we plan: 1) To continue with the THz spectroscopic and imaging studies on pharmaceuticals and building materials ensuring their quality and safety for humans and the environment. THz spectroscopy and imaging will be used to study changes in the chemical structure of drugs, anomalies, and deficiencies in pharmaceutical packaging, and the homogeneity of the tablets or capsules of drugs that will be exposed to various environmental conditions. THz waves will be used for the characterization of traditional and alternative building materials as well as construction and demolition waste. The refractive index and absorption coefficient of various common building materials in the frequency range between 600 GHz and 6 THz will be studied, as accurate knowledge of these material parameters is essential for modelling THz wave propagation in media for future wireless communication systems at higher frequencies beyond the 5G telecommunications. 2) To research the physical properties of materials and to develop experimental techniques that are required for such investigations. The material research will be focused on high entropy alloys, multiferroics, and molecular magnets, while nuclear quadrupolar resonance (NQR) will be used for the detection of selected counterfeit medicines. For the detection of NQR signals at larger distances much larger coils system will be designed. 3) To develop numerical algorithms in the field of imaging in biophysics, NQR, and civil engineering. The optically pumped magnetometers that operate at room temperature are proposed to replace SQUID-based magnetometers that required cooling down to 4 K for the imaging magnetic fields originating from the brain. The suitability of building straw bale houses in a cold climate will be evaluated experimentally and theoretically.
