A British company has demonstrated a prototype device capable of stopping cars and other vehicles using a blast of electromagnetic waves.

The RF Safe-Stop uses radio frequency pulses to "confuse" a vehicle's electronic systems, cutting its engine.

E2V is one of several companies trying to bring such a product to market.

It said it believed the primary use would be as a non-lethal weapon for the military to defend sensitive locations from vehicles refusing to stop.

There has also been police interest.

The BBC was given a demonstration of the device at Throckmorton Airfield, in Worcestershire.

Deputy Chief Constable Andy Holt, of the Association of Chief Police Officers (Acpo), who has evaluated the tech, said the machine had "potential, but it's very early days yet".

"It's a small radar transmitter," said Andy Wood, product manager for the machine.

"The RF [radio frequency] is pulsed from the unit just as it would be in radar, it couples into the wiring in the car and that disrupts and confuses the electronics in the car causing the engine to stall."

He did not provide other specifics. However, the Engineer magazine has reported the device uses L- and S-band radio frequencies, and works at a range of up to 50m (164ft).
