RF/Wave Absorbers

With the trend of fast speed and more functions in compact electronic design, excessive EMI decreases systems and components performance, and even fails the operation.
RF/Wave absorbers are used to solve a wide variety of problems such as internal cavity resonances, antenna pattern shaping, and high-frequency interference.
Our different absorber materials are categorized into two types: resonant absorbers and broadband absorbers. Resonant absorbers are designed for desired frequency. The broadband absorbers work on a broad spectrum.

FS/FM Series

FS/FM series absorbers' base material is polyurethane foam with precise open cell structure. Special dipping process makes its surface match the dielectric properties of the corresponding frequency range. Open cell size can be optimized to tune the E-field loss and reduce reflection to certain frequency range.There are two types of foam absorbers, single-layer foam absorber (FS series) and multi-layer foam absorber (FM series). Their main application function is to provide isolation around the antenna or to reduce side lobe. They can be cut into shapes to fit inside microwave cavity to reduce interference or used inside radome, test box and network enclosure as air filtration and EMI shielding complex.

Silicone Based

ABS5000 Series

NYS-SORBER ABS series microwave absorbers are in thin sheet form loaded with magnetic fillers. Nystein specially designs this series products for reflection attenuation of high incident angle wave. Products are suitable for 2 to 40GHz frequency wave absorbing. The silicone elastomer substrate stands high temperature, and is oil resistant and fire retardant. The special magnetic particles fillers make the products excellent microwave absorbing capability when the incident angle is over 65 degrees. NYS-SORBER ABS series is used to reduce microwave resonance inside enclosure and cavity "Q" value. Also, it could effectively isolate bottom plate and antenna. Together with additional EMI materials, it provides perfect solution for EMI shielding in 2 - 40GHz frequency range. Refer to the following corresponding Return Loss Curve for specific product performance.

Dispensable

LAS2-C1001

LAS2-C1001, a carbonyl iron powder loaded material, is a two component room temperature curing silicone paste. It is developed to be used in applications that require reduction of electromagnetic interference (EMI) in wide frequency range such as mold waveguide terminations, attenuators, and loads to size. One of the superior feature of LAS2- C1001, is filling irregular gap, space and small aperture which its counterpart gaskets cannot offer. And also dispensability determines its high volume mass production efficiency.

Soft Magnetic Shielding Materials

MI Soft Magnetic Material

MI soft magnetic material is a high permeability and high magnetic loss material covering 100K to 8GHz wide frequency range. Substrate resin is filled with high loss absorbent and metal molecules. Molecules are re-arranged in order by special process. This material can restrain EMI waves bouncing back and forth. Noises then are converted to heat. This creates a clean EMI environment while maintaining electronic system normal operation.

Thermal Microwave

AB Series

Thermal microwave absorber, as the name implies, can both absorb microwaves and conduct heat. With polymer silicon as substrate, thermal microwave absorber is a compound of ceramic powder, magnetic filler and corresponding additives. The product can achieve thermal conduction and microwave absorption at low compression force, and it has good insulation properties and environmental stability.
