Review of: "Nano Antennas and Many Properties (Radiation Pattern Characteristics, Radiation Resistance and Reactance)"

One of the most important parameters of any nanoantenna is the current distribution on it.This characteristic determines the radiation pattern, radiation resistance and reactance, and many important properties of the antenna.Despite the possibilities of making nanotubes with a length of several centimeters, it is possible to make electrical conductors with a length-to-width ratio of the order of 10^7 .Nanotube antennas at rst glance give us the impression that they are similar to the dipole antenna designed in small dimensions.But in fact, this is not the case.In the original theory of dipole antennas to determine the current distribution on the antenna, the dipole radius is larger than the skin depth and the resistance losses are so small that they can be ignored.Since the nanodipole L/d is signi cantly reduced, it becomes unusable.In one-dimensional electrical conductors such as nanotubes, the skin depth mode is completely eliminated.Because here the electrons are only Qeios qeios.com
