DESIGN OF THz FREQUENCY RANGE DEVICES BASED
ON TWO-DIMENSIONAL AND THREE- DIMENSIONAL METAMATERIALS
Application
- Broadband polarization converters which have a metamaterial structure and function within a wide range of THz spectrum.
- Polarization rotators based on a metamaterial much thinner in comparison with traditional elements.
- Polarization filters of THz radiation based on a thin metamaterial.
- Electromagnetic wave absorber in the THz range.
Description
As a result of theoretical studies and computer simulation, a number of metamaterial test samples have been designed and produced on the basis of micro-sized flat and three-dimensional resonance elements in the THz frequency range.
Implementation level
Test samples (advanced prototypes) of a two-dimensional metamaterial on silicon substrate for THz range with conducting aluminum and molybdenum elements were made at JSC «INTEGRAL». Experimental studies have been carried out and it has been proved that the designed and fabricated metamaterial with pre-calculated parameters shows predicted frequency and polarization selective properties.
