A -- FREQUENCY SELECTIVE MATERIALS FOR CONTROL OF RADIATED EMISSIONS AND INTERFERENCE SUPPRESSION SOL DTRA01-00-R-0023 POC Marilyn F. Williams, Contract Specialist (703)325-1193; Donald L. Shires, Contracting Officer, (703)325-6684 E-MAIL: donald.shires@dtra.mil, marilyn.william@dtra.mil. Procurement Summary: The Defense Threat Reduction Agency (DTRA) has a requirement to fabricate samples of frequency selective materials, provide specific omni-directional designs using geometric construction, and perform laboratory tests to establish actual shielding performance of the materials. This requirement will support an effort to maximize control of radiated emissions and interference suppression in regard to systems that must reliably operate in a battlefield environment, which would includes a wide spectrum of electromagnetic (EM) environments. The design and development of these materials must incorporate the capability of passing the appropriate battlefield signals and blocking the damaging electronic attack frequencies (i.e., HPM, EMP, etc., all of which typically lie below 4GHz) in order to successfully protect future military electronics. This effort will only address a subject system which is susceptible and subject to interfering external fields below approximately 4GHz, yet requires no attenuation of signals at or above 8GHz. The direct program objective will be the development of one or two application specific materials. Additionally, the program will develop, document, and test a design method for low and high pass materials. The objective encompasses the development of two application materials and designs, and theoretical proof of field operability of both the designs and materials. The developmental objectives will include (1) geometric construction using conventional conductors, (2) frequency selective materials, (3) multi-layer structures and coatings, and (4) a combination of shielding technical (EM shields, filter and electrical surge arrestors) to block external fields below 4GHz, yet requires no attenuation of signals at or above 8GHz. The contractor is required to explain the theory behind each construction with respect to the said frequency range, investigate and incorporate, if applicable, the use of conductive polymers to achieve the frequency selectivity. The solicitation is expected to result in a single award of a cost type contract. The Standard Industry Code (SIC) is 8731, and the small business size standard is 500 employees. Requests to obtain a copy of solicitation number DTRA01-00-R-0023 shall be e-mailed to: marilyn.williams@dtra.mil. The solicitation request shall include your company name, point of contact, address, phone, fax, and e-mail address. The solicitation will be electronically transferred to the forwarded addressee. The anticipated level of effort is approximately 8 man-months with a 16 month period of performance. This is a 100% total Small Business Set-Aside solicitation. The estimated release of this solicitation is 12 May 2000. Posted 04/17/00 (W-SN445654). (0108)
