Microwave Absorbing Materials (Rubber)Our Rubber Microwave Absorbing Materials used hexagonal ferrite, metal alloy composite ultrafine particles, Fe-based nanocrystalline flake particles and magnetic properties of absorbent fibers, such as magnetic as the absorption medium; the use of excellent heat resistance, ozone resistance of chloroprene rubber, the best heat resistance and chemical resistance of the fluorine rubber, oil resistance, and excellent mechanical properties of polyurethane rubber as matrix resin, prepared by. Rubber sheet on each layer of the interference wave reflection or absorption, resulting in different phase of the superimposed interference wave attenuation, and absorption in vivo exchange of magnetic media and electromagnetic wave energy, geothermal energy, scattered and lost into.
Main features: thin, flexible, and the absorption rate is high, a good low-frequency characteristics (900MHz ~ 40GHz), high intensity, good stability (-50 ~ 150°C).
The main application areas: communications and radar clutter suppression, RCS reduction, such as 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.
