Nokomis, Inc. has been awarded a DOE SBIR Phase I grant for "Graphene as a Coating Material for High-Power RF Windows."


In recent years, one of the major impediments to the progress of high power Radio Frequency (RF) generation for particle accelerators, high power radars, communications systems and directed energy has been the lack of an RF window option exhibiting the key properties required for reliable performance at extreme power levels. This research conducted by Nokomis will develop an innovative RF window coating structure to overcome these deficiencies. Building upon Nokomis expertise in RF product development, the new windows will allow for greatly improved power handling capability.


A significant portion of global research in particle physics is based on data produced at the few major particle accelerator laboratories located around the world. The success of this research will provide these key facilities major benefits in terms of quality of data collection, lower bottom line project costs, which results in the availability of more and better data for analysis by the many interested research institutions. Beyond that, the applications for this technology includes a wide range of defense, space, energy, communications, medical, research, and security applications that will benefit from improved window performance and reliability.


“Materials research for RF applications is a very rich area for scientific, industrial and military advancement. Graphene has unique material properties that can provide high performance RF coatings that are unrivaled compared to current scientific, industrial and military solutions, “noted Walter J. Keller, Chief Executive Officer of Nokomis,” We’re extremely excited by this highly innovative and unique work and the potential it holds for significant advancement.
