Difference between nanotube antennas and classic antennas ( wave speed in nanotubes is about one hundred times slower than the speed of light)

Note : Many features make nanotube antennas behave very differently from classical antennas. The main difference is that the current distribution is alternating with a wavelength that is 100 times smaller than the free space wavelength for a given thermal frequency. The wavelength of the current distribution depends on the wave speed in that mode.注意：诸多特性使得纳米管天线（nanotube antennas）的运行特性与经典天线（classical antennas）存在显著差异。二者最核心的差异在于，其电流分布呈交变形式，且该电流分布的波长相较于给定热频率下的自由空间波长（free space wavelength）小100倍。电流分布的波长取决于对应传输模式下的波速。
