Application of spray and infusion absorbing materials, absorbing sealants, inks, and coatings

1. Flexible and thin magnetic loaded rubber absorbing material: tuned frequency absorbing material

Tunable frequency absorbing materials, or resonant frequency absorbing materials, have the characteristic of significant reflection loss at discrete frequencies, with a typical attenuation of up to 20dB. Tunable frequency absorbing materials provide narrowband absorption characteristics from 1 to 40 GHz.

2Cavity resonant absorbing material 
The cavity resonant absorbing material is designed to exhibit high loss characteristics when placed in a microwave cavity. Absorbing materials will effectively reduce the Q factor by attenuating cavity resonance, resonant frequency, or harmonics. At frequencies ranging from 1 to 20 GHz, cavity resonant absorbing materials can absorb electromagnetic wave energy incident from normal and high angles.

3RF absorbing foam material

○ Surface wave absorbing materials

Surface wave absorbing materials are synthetic rubber absorbing materials with the strongest magnetic load. Surface wave absorbing materials are designed to have the highest loss characteristics and are used to be laid on conductive or metal surfaces to absorb traveling waves or surface waves. Surface wave absorbing materials can absorb traveling or surface wave energy from 1-20 GHz.

○ Low frequency absorbing materials

Low frequency absorbing materials have high attenuation characteristics in the sub microwave frequency range. The material is made into magnetic particles of various shapes, exhibiting high magnetic permeability in the frequency range of 1 MHz to 3 GHz.

4Flexible medium foam absorbing material

○ Mesh foam wave absorbing material

Mesh foam absorbing material is a very light conductive carbon loaded sheet material, which can achieve a large attenuation of normal and deviating normal incident electromagnetic waves. The mesh foam material is processed by a continuous gradient coating, which has the characteristics of broadband reflection loss in the frequency range of 1~20 GHz.

○ Damaging foam absorbing material

The lossy foam absorbing material is a lightweight, low-cost carbon loaded plate. It is processed with a uniform coating and has high insertion loss characteristics in the frequency range of 1 to 20 GHz.

5RF absorbing material

○ Curled foam absorbing material

Curly foam absorbing material is a lightweight carbon loaded sheet material, whose geometry is similar to a "egg tray". The conical structure on the material enables high reflection loss from 1-20 GHz.

6Spraying and infusion of absorbing materials

○ Absorbing sealant, ink, and coating

Absorbing coating materials can be used for various application technologies, such as spray coating, injection coating, or immersion coating. This material can be processed from one or two parts of materials with various viscosities
