Amplitude modulation. It is the modulation method to transmit information by using strength of the amplitude of the carrier wave. The electro-magnetic wave that applied AM modulation has narrow frequency compared to FM modulation method, and has advantage of easy transceiver circuit structure besides more.

There are three mechanisms of removing material: grinding, polishing and lapping. They differ in the tendency to introduce.
The most common metallographic abrasive used is Silicon Carbide – SiC. It is an ideal abrasive for grinding because of its hardness and sharp edges. For metallographic preparation, SiC abrasives are used in coated abrasive grinding papers ranging from very coarse 60 grit to very fine 1200 grit sizes. Some of the.

For polishing, it is beneficial to use a disc grinder (for example, Gatan disc grinder, Model 623) as it offers the removal of material with good control (viz., in steps ... using a liquid nitrogen (LN2) stage, or by employing the ion beam modulation feature in which the sample is not exposed to the ion beam continuously. In a Duo.
Finally, the surface of the sheets was cleaned and polished until the surface roughness is around 1 nm by using both rough grinding (choosing abrasive paper from 600 Mo to 3000 Mo in sequence) and elaborated polishing (using 5 μm, 1 μm and 0.05 μm alumina suspension as the polishing agent). (B) Film Deposition.
