Electromagnetic Nanofield and Planck Frequency

Planck's relation isn't quantum in intrinsic manner because of frequency that changes with continuity into a largest range of frequencies that includes classic electromagnetic waves, microwaves and nanowaves. These last are placed inside spectrum after microwaves and they are associated with electromagnetic nanofield. The distinction between micro and nanowaves enables to define Planck's frequency that is the threshold frequency between the two types of wave and it is located where microwaves end and the infrared band begins (300GHz). Planck's frequency enables to complete the effective quantization of Planck's relation because for energy quanta frequency cannot be smaller than Planck's frequency.
