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.
2.1. 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)
(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.
