Adisyn recently completed an initial proof-of-concept program demonstrating that graphene-enhanced composite materials can reduce radar reflection characteristics, with laboratory testing confirming up to 20dB reduction in radar reflection.
The program was conducted in collaboration with Ramot, the technology transfer company of Tel Aviv University. Composite samples were tested under controlled laboratory conditions and demonstrated up to 20dB reduction in radar reflection coefficient relative to baseline materials. The research team is now working on further optimization, targeting up to a 30dB reduction. According to Adisyn, a reduction of that magnitude would shrink the actual physical radar cross-section – the size of a target as detected by radar – by a factor of 1,000.
To put that in practical terms: if a drone originally appeared to a radar system as a one-square-meter object, a 30dB reduction would mean it reflects radar waves with the intensity of an object measuring only 10 square centimeters, roughly the size of a large insect.
The company sees potential applications across the Unmanned Aerial Vehicle (UAV), defense, aerospace and advanced composite materials markets, where radar signature management is a key design consideration.
Adisyn pointed to two tactical advantages such technology could offer. The first is shrinking the reaction window available to defensive systems. Even if a drone is eventually detected, late detection means interception systems such as rapid-fire anti-aircraft guns or jammer networks would have only seconds to lock on and engage.
The second advantage relates to ground clutter. Small drones already fly at low altitudes and use terrain masking to avoid detection. Combining low-altitude flight with a 30dB radar reduction could make a drone effectively invisible to many terrestrial radar systems, as its signature would be lost among ground reflections.
Adisyn's Managing Director, Arye Kohavi, noted the company is at an early stage of technical validation for the radar program. The Board considers that successful optimization could position the company within a specialized segment of the advanced 2D materials market focused on signature-aware composite systems.
Following completion of the proof-of-concept, the research team will continue laboratory optimization work. Further validation would be required to assess scalability, performance consistency and commercial viability before any commercialization pathway becomes clear. Under the existing collaboration framework with Ramot, Adisyn holds a 12-month option to receive exclusive, perpetual rights for the technology, subject to agreed terms.
The radar signature initiative leverages Adisyn’s graphene materials expertise but does not change the company’s primary focus, which remains the development and commercialization of its low-temperature Atomic Layer Deposition (ALD) graphene technology for semiconductor interconnect applications.
The company indicated its semiconductor interconnect program is on schedule and that shareholders would receive a separate update on progress in the coming weeks. Adisyn has previously flagged to investors that alternative industries could benefit from its core graphene deposition technology.
The radar program is being advanced as a parallel but secondary stream to the semiconductor opportunity. It could provide additional commercial opportunities that capitalize on Adisyn’s capability in graphene.
