Basic Physics for Wireless Communications - Electromagnetic Wave

With the development of science and technology, radio wave applications have penetrated into every aspect of our lives!
Radio/TV; mobile phone communication, Wi-fi Bluetooth, infrared remote sensing.
To understand wireless transmission, first we need to understand the basic physical knowledge: electromagnetic waves.
