Microwave Absorbing Materials (Foam)Our Foam Microwave Absorbing Materials is the electromagnetic wave-transparent materials and absorbent composites formed. Wave-transparent materials include poly urethane, polyethylene, polystyrene, polycarbonate, polypropylene and other plastics, but also the main body of foam; electromagnetic wave absorbers, including carbon powder, carbon fiber, graphite, ferrite (It is also very good wave-transparent materials and dielectric materials), etc., but also to add some flame retardants. Porous foam structure, as much as 30 times the density of the foam, it can fully absorb the electromagnetic waves that gap. Obturator-type structure to avoid moisture absorption, to avoid damp electronic components.
Main features: light weight, flexible, and good absorption performance.
The main application fields: radar and microwave communication system clutter suppression, anti-electromagnetic interference, microwave anechoic chamber and other technical fields.
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.
