Cuming Microwave Corporation was formed to focus on technology products for

the RF and the EMC industry. We manufacture absorber materials, we design

and install anechoic chambers for all RF and EMC applications, and we provide

a team to offer full turn key solutions.

In addition, we provide a very broad line of specialty absorber products based

on magnetic and dielectric lossy materials, and also provide low loss dielectric

materials, for applications ranging from space to supersonic airborne to

subsea naval.

Founded in 1980 by noted, material scientist Dr. William R. Cuming, Cuming

Microwave Corporation provides innovative materials for the electronics and

microwave industry. Our microwave material manufacturing facility is located

in Avon, Massachusetts, USA.

Cuming Microwave engages in extensive research and development activities to

provide customers with cost-effective and creative materials for their specific

applications. Custom engineered products and solutions are our specialty.

Microwave Absorbers, Shielding Materials and Specialty Dielectrics Applications

Foam Absorbers

Flat, thin dielectr ic radar absorbers, foam based. Products are eithersingle or mult i - layered foam that are electr ical ly graded or separatedby resist ive f i lms. Excel lent broad-banded and off -angle performance.Some products have Fire Retardant versions avai lable. Products areused for reducing RCS, preventing unwanted ref lect ions and el iminating inter ference.

Rubber Absorbers

Radar absorbing t i les or sheets that are tuned to specif ic frequencies or frequency bands. Materials are avai lable in a select ionof resins: s i l icone, urethane, nitr i le and neoprene. Good for RCSreduct ions, antenna signal shaping, el iminate unwanted RF energy in electronic modules.

Liquid & SprayableAbsorbers

Coatings designed for suppression of RF waves and cur rents travel ing along conductive sur faces, and for RCS reduct ion. Products are paint - l ike coatings that can be brushed or sprayed onto sur faces and complex shapes. Some products avai lable as cast ing materials for suppression of energy in electronic units. Products are avai lable in epoxy; s i l icone or urethane based resins. Thickness of material is dependent on frequency of use.

Honeycomb & High Power Absorbers

Radar absorbers designed to operate at high temperatures andpower. Power rat ings > 10 Watts/Inch2, with proper venti lat ion canbe handled. Materials are l ightweight and can be used for structuralstrength and incorporated into the load-bearing parts of aircraft,ships and vehicles. Materials can be fabricated with pyramid shapesfor use in anechoic chambers.

Syntactic Foam

Lightweight dielectr ic and art i f ic ial dielectr ic materials or lossy materials using microbal lons and resins. Dielectr ic propert ies are control led to t ight tolerances. Appl icat ions include airborne appl icat ions such as antennas; under water appl icat ions and decoys where low weight is a factor.

Specialty Products

Cuming Microwave offers custom, engineered products for uniqueappl icat ions. Products and ser vices include radar absorbing structures; appl icat ion of peel & st ick adhesive (PSA) for ease of assembly; die cut parts to customers’ drawings; and engineered products developed for appl icat ions where standard products don’t meet the cr i ter ia. Cuming Microwave offers an RF PROBLEM SOLVER KIT for laborator y use. It includes many of the common products for quick lab evaluation.

Anechoic Chambers & Absorbers

Cuming Microwave Corporat ion offers an extensive l ine of high performance absorbers, in convoluted and pyramid shape for maximum performance. These materials are designed for use in anechoic chambers, ranges and test boxes. Materials are avai lable from 20 MHz to > 100 GHz. Cuming Microwave offers design, construct ion and turn-key instal lat ion of anechoic chambers.

Dielectric Materials

Materials with control led dielectr ic constants and low loss tangents.Products have unique dielectr ic and physical propert ies, and areavai lable in var ious forms; foam; r igid sheets, bars and rods; l iquidsand foam-in-place. Dielectr ic materials can be used for dielectr icspacer or c i rcuit substrate, tapered permitt iv ity transit ion, radome,RF lens, or other uses where a machined part of a specif ic dielectr ic constant is needed.

Cuming Microwave Corporation was formed to focus on technology products for

the RF and the EMC industry. We manufacture absorber materials, we design

and install anechoic chambers for all RF and EMC applications, and we provide

a team to offer full turn key solutions.

In addition, we provide a very broad line of specialty absorber products based

on magnetic and dielectric lossy materials, and also provide low loss dielectric

materials, for applications ranging from space to supersonic airborne to

subsea naval.

Founded in 1980 by noted, material scientist Dr. William R. Cuming, Cuming

Microwave Corporation provides innovative materials for the electronics and

microwave industry. Our microwave material manufacturing facility is located

in Avon, Massachusetts, USA.

Cuming Microwave engages in extensive research and development activities to
