"THz splitting, as modulator, generator of THz vortex beams... 2 varifocal Fresnel zone plates side by side rotated relative to each other, enabling focusing THz radiation and tuning plate's properties by stretching... thin film carbon nanotube based plate twists wavefront of THz passing through it... changing radiation intensity distribution, splitting beam into several modes of different intensities for information transfer channels... interaction of different nanotube patterns... medicine (X-ray alternative), 6G, microscopy"
