Microwave Absorbing Materials (Coating)Coating Microwave Absorbing Materials include absorption, interference and resonance type, the electromagnetic wave absorption medium is conductive powders, when the external electromagnetic waves incident upon the surface of materials, dielectric materials under electromagnetic field generated in the conduction current or displacement current by finite conductivity, allowing access to the coating of the electromagnetic energy is converted to heat loss out, or through magnetic dipole moving in the electromagnetic field by the limited role of permeability can be converted into the electromagnetic energy loss out.
Main features: thin and wide absorption band (2 ~ 18GHz), good absorption characteristics at mirror wave and surface wave. Suited to the complexity of the construction surface.
Main application: RCS reduction, anti-electromagnetic interference.
Microwave Absorbing Material Design Principle and Absorption Mechanism
►The material using nano-materials, planar hexagonal ferrites, amorphous magnetic fiber, particle film as a high-performance absorbent absorbing medium;
►Using a new absorption principle - electric magnetic and eddy current losses, the thickness of absorbing materials prepared in thin, light weight, absorption band and absorption rate is high;
►According to MAXWELL equations, using genetic algorithms (GA), to achieve simulation of electromagnetic wave absorbing materials (CAD), maximize the absorption of dielectric properties, and shorten the development cycle of materials can meet the special needs of the user.
Microwave is the 300MHz-300GHz frequency electromagnetic waves are radio waves in a limited band of short wavelength that is 1 meter (excluding 1 m) to 1 mm between the electromagnetic wave, which is the decimeter and centimeter wave, mm wave collectively. Microwave frequencies than the average high frequency radio waves, often referred to as "ultra-high frequency electromagnetic waves." The basic nature of the microwave is usually presented as the penetration, reflection, absorption of three properties. For glass, plastics and ceramics, microwave is almost through without being absorbed. For water and food will absorb the microwave, and makes self-heating. The pairs of metal things, will be reflected microwave.
FRD absorbing material is "electric magnetic and eddy current loss-type absorbing mechanism" refers to the loss of electromagnetic wave into the absorbing material inside the material effectively absorb the energy is transformed into heat or other forms of energy and dissipation away.
