What we do
Seven funded projects with the UK Defence Science and Technology Laboratory and the Home Office, and the markets where this kind of sensing actually gets used.
Track record
Proof of concept for sub-wavelength radio frequency imaging.
Detection of an explosive proxy concealed in shoes.
Enhanced RF imaging using a unique antenna configuration.
Development of a hybrid RF thermal acoustic imaging system.
Demonstration of an ELF (under 1 kHz) imaging system with centimetre resolution.
Demonstration of a frequency-agile RF sensing system.
Riverbed profiling and ground bearing capacity measurement from a drone-mounted probe.
Markets and applications
Body scanners at major airports are expensive enough to justify only at the highest-value, highest-traffic pinch points, which leaves smaller airports and other public spaces effectively unscreened. Low-cost, portable, human-safe screening closes that gap rather than trying to shrink an existing scanner.
Bases built or moved at short notice in a conflict zone still need to screen local personnel entering under a hearts-and-minds posture, without the cost of a millimetre-wave scanner. The same sensing measures ground bearing capacity for roads and bridges remotely, in place of the usual hazardous manual steel-rod test.
Human-safe RF screening can sit at a passport check without adding a separate step, or scan through the sides of a soft-bodied lorry or the inside of a tyre wall, unaffected by rain, to identify concealed contraband.
RF fields at these levels are intrinsically human-safe and penetrate tissue readily. A low-cost first-layer triage tool built on that, sitting in a GP surgery or a first responder's kit, could spot a major trauma before the patient reaches hospital. It isn't aiming for MRI or CT resolution, just a faster first read.
Ageing concrete infrastructure needs monitoring without the disruption and penalty costs of shutting a road to inspect it. Underwater and marine structures are even less served: RF propagates through roughly a metre of water, opening up drone or diver-free surveying where divers are currently the only option.
Engagement
The projects above and the applications they sit in are backed by two working instruments you can try yourself, one for RF and one for infrared. Both are on this site, driven by the same physics as the fieldwork.
