(Nano Telecommunication) Flow generation by Rectenna nano method

Note: Combining optical antennas with a suitable rectifier system called Rectenna for short. It is used in nano-communications and   power transmission in  the microwave band. It is also used in the production of nano electrical energy.

This compound  has been introduced to convert solar light  energy into electrical energy and is rapidly being developed and  researched. While the efficiency of common solar cells on the market  is around 30% at best, it yields two to three times that amount  for rectangles. It should be noted that Rectna has been used in recent years, especially in the field of power transmission in  the microwave band. For example, in theory  , for a single frequency of 9.2 GHz, more than 10% efficiency is predicted  . Of course, the practical efficiency of making these devices may  be slightly different, and the terahertz nanofrequency transmittance must be determined in practice.

A dipole antenna with linear polarization and length 2 / λ, which has a relative bandwidth of 11%, will be able to collect about 75.2 pW. Due to the low power reception of each independent antenna, the use of anti-arrays in this cell is common, which also has its own rules and methods. The antenna is a device that can receive electromagnetic waves in space. To receive electromagnetic waves Solar by antenna The dimensions of the antenna should be in the order of the size of the input wavelength to its surface, so in order to receive solar radiation that includes wavelengths in the infrared, visible and ultraviolet region, an antenna with nanometer dimensions is needed. Optical nanoantennas for solar energy collection offer a practical solution that is more efficient than other common photovoltaic technologies such as solar panels, leading to rapid development in The industry has been nanotechnology and optical materials. When a solar electromagnetic wave hits the surface of a nano-antenna, a time-varying current is generated on the surface of the nano-antenna, resulting in a voltage generated at the power supply slot. The desired DC power is generated. In the solar rectane system, millions of nano-antennas with a suitable rectifier are placed next to each other and each of them generates electrical energy separately using sunlight. Conversion of solar luminous energy that It is absorbed by the antenna, it is done by  a suitable rectifier. Suitable diodes for this frequency range are 12 MIMs. Because nano-antennas have the ability to absorb a wide angle, even  if the sun is inclined to the surface of the solar panel, their efficiency is up toSignificantly maintained. The system can also absorb energy radiated from the ground, or ground radiation, caused by the sun's  daily radiation to the earth's surface, occurring at lengths of 10 micrometers , or frequencies of about 90 terahertz, for this  reason . Nanoantennas of the solar recton system can also generate electricity by collecting this radiation during the night or in bad weather conditions  .

Conclusion :

Combining optical antennas with a suitable rectifier system called Rectenna for short. It is used in nano-communications and   power transmission in  the microwave band. It is also used in the production of nano electrical energy.
