1. Main Research Areas.

1.1. Study of materials and substances in the millimeter (MM) and submillimeter (SMM) ranges (including experimental and theoretical investigations).

1.2. Electrodynamics of wave guiding and radiating structures and MM- and SMM-range devices based on such structures.

1.3. Application of MM and SMM waves to material-composition testing (including water content monitoring), introscopy, communication and radar systems, medical, industrial, and other problems.

2. Possible topics of cooperation on the basis of the completed and current works of the laboratory.

2.1. We have an extensive data bank on complex refractive indices (n* = n - ik) and other characteristics of various materials (liquid and solid dielectrics, liquid crystals, semiconductors, ferrites, composites, polymer nano-composite, different nanomaterials, building, natural, and common use materials) for the MM and SMM ranges. We have a set of devices for the measurement of the before mentioned materials. These instruments allow us to measure n in the interval 1.05 - 20 and tan δ = 2n/(n2 - k2) in the interval 1.0 - 10-5 in the range of wavelengths from 10 to 0.6 mm. Also, the theoretical insights and theories for series of absorption (dielectric loss) mechanisms had been developed.

2.2. Prospective transmission lines for MM and SMM ranges (dielectric, ferrite, semiconductor waveguides, new metal periodic structures, quasi-optical beam waveguides), passive and active components and systems based on these lines have been worked out and studied. Each line from this set offers specific advantages (simple design, low weight and cost, technological versatility, high technical characteristics, etc.) depending on their applications.

2.3. We suggest a cooperation based on topics 2.1 and 2.2 in the following areas:

(a) creation of devices for testing water solutions (alcohol in water, sugar in water), water emulsions (e.g., water in crude oil);

(b) creation of devices for determination of water content in solid materials and substances (water in paper, in porous materials, and powders, e.g., grain, powders employed in metallurgy);

(c) creation of devices for application of MM waves in medicine;

(d) working out of nonreflecting frequency and polarization sensitive screens, including electronically and optically controlled gratings.

(e) investigations of materials for radomes and antenna reflectors;

(f) creation of electronically controlled phase shifters, attenuators, power dividers, and other components for MM-wave antenna--feeder structures;

(g) design of power combining systems based on open resonators and guiding structures for power combining of solid state sources;

(h) theoretical and experimental studies of the nature and properties (frequency and temperature dependencies) of main contributing losses in various dielectrics (including low loss materials), semiconductors, ferrites, bio-liquid, bio- tissue, nanonaterials, liquid crystals.
