In ground wave propagation, radio waves travel along the surface of the Earth, following the curvature of the planet. Freq Range: 30 kHz to 300 kHz (Low Freq). Key Points: Travels along the ground. Strongly attenuated by terrain, trees, buildings, etc. Limited to short distances (few hundred km). APPS: AM radio (MW band). Navigation systems & military communication.In sky wave propagation, radio waves R transmitted towards the ionosphere, which reflects or refracts them back to Earth. Freq Range:

Chemical vapour deposition, a hybrid method using chemicals in vapour phase is conventionally used to obtain coatings of a variety of inorganic or organic materials.It is widely used in industry because of relatively simple instrumentation, ease of processing, possibility of depositing different types of materials and economical viability.Under certain deposition conditions nanocrystalline films or single crystalline films are possible. There are many variants of CVD like Metallo Organic CVD (MOCVD)
