CORROSION-RESISTANT RESONANT MICROWAVE ABSORBER
Eccosorb DSF is a thin, flexible, narrow band absorber that reflects -20 dB or less of normal
incident microwave energy at the design frequency in the range of 3 to 22 GHz. Eccosorb
DSF is a dielectrically loaded, silicone rubber sheet. Unlike typical iron-filled silicone
absorbers, no oxidation is possible due to the chemical nature of the patented dielectric
pigmentation system. The material is impervious to moisture and can be used outdoors.
FEATURES AND BENEFITS
• High power performance
• Narrow band performance
• Oxidation-resistant
MARKETS
• Commercial Telecom
• Security and Defense
• Automotive

APPLICATIONS
• Eccosorb DSF is ideally suited for applications requiring absorption at a specific frequency
or in a narrow frequency band, including:
-lining radar nacelles, particularly where high power is present
-attaching to masts of ships, walls, etc. to reduce reflections and echoes to nearby
antennas
-attaching to vehicles to reduce overall radar signature.
• Eccosorb DSF is especially recommended for use in saline environment where oxidation
may be considered a problem. The materials are impervious to salt water and can be used
in marine applications.
AVAILABILITY
• Standard sheets are 305 x 305mm (12”x12”).
• Thickness depends on resonant frequency desired.
• Grades are designated by their suffix corresponding to the resonant frequency desired.
• Other resonant frequencies can be supplied on special order.
• The material can also be supplied in customized shapes.
