What is Microwave?

Microwave is the frequency of 300 MHZ ~ 300 GHZ electromagnetic wave, it is short radio waves in a limited frequency band, the wavelength between 1 mm ~ 1 m electromagnetic wave, it is generally referred to as the decimeter wave, centimeter wave and millimeter wave. Microwave frequency is higher than general radio frequency, often also referred to as "ultra high frequency electromagnetic wave. As a kind of electromagnetic wave of microwave also have wave-particle duality. Basic properties of microwave usually appears as transmission, reflection and absorption three characteristics. For glass, plastic and porcelain, microwave is almost through without being absorbed. For water and food, etc. will absorb microwave and heating by itself. For metal stuff, it will bounce back the microwave.

Microwave heating principle.

Microwave heating is an object absorbing microwave energy which can be converted into heat energy, which is completely different from other conventional heating methods.The traditional heating method is according to the principle of heat conduction, convection and radiation heat from the outside to the material quantity of heat, heat always passes of the heating material, its excellent material inevitably exist in the temperature gradient, so the uneven heating of the material, the material in local overheating;Microwave heating technique and traditional heating mode is different, it is through the heated body internal dipole molecule high frequency reciprocating motion, the internal friction heat and the heated material temperature, no heat conduction process, can make the material internal and external heating, heating up at the same time at the same time, heating speed and uniform, only traditional heating mode is one of the energy consumption of a few minutes or a few points to achieve heating.From the theoretical analysis, the amount of heat generated in the microwave field has a lot to do with the types of matter and their dielectric properties.
