The development of UHF antenna devices for high data transmission rates is topical nowadays due to the overload of the explored radiofrequency range. In this paper, we describe the concept of optical antenna which can be used in terahertz frequency. It is based on diffraction grating theory and the ability of semiconductors to change their conductivity under light illumination.
The formation and constant upgrade of educational programs is the essential part of education process. In modern world, new devices, methodologies and ideas appear very rapidly and educational process must respond to them. One of the fast developing fields is the field of telecommunication. Since the well-known radiofrequency range is overloaded, achieving higher terahertz frequency ranges becomes...
