3.Within HF band, Bragg scattering occurs when Hertzianwaves refract ocean surface-waves, thus over-the-horizon radar is widely used to remotely sensing ocean surface-waves, and ship detection can be done by increasing the ratio of signal to sea-echo Doppler spectrum.
4.This article introduces the method of using inductorium to do the demonstrational experiment of Hertzianwaves which has a good experimental effect and is interesting and is able to play a better role of aid teaching.
