Description:
A Spanish research group focused on innovative and customized solutions for communication systems has developed an extremely precise system to measure angular displacements and angular velocities which can withstand large environmental changes.

This system is based on different principle for microwave and sensing based on the symmetry-related electromagnetic properties of transmission lines loaded with symmetric metamaterial resonators. The reason for such a major robustness, as compared to the previous conventional sensors, is that the novel sensors are based on symmetry disruption.

If symmetry is perturbed by any means (lateral displacement, rotation, asymmetric dielectric loading, etc.), then this perfect cancelation of electric and magnetic field components vanishes, a net coupling arises, the particle is driven, and the transmission coefficient exhibits a notch at the fundamental split-ring resonator (SRR) resonance (Fig. 2). Moreover, the notch magnitude depends on the level of asymmetry.

Increasing the number of resonators means to reduce the resonator transverse dimension and the inter-resonator spacing. A mínimum transverse dimension is necessary to guarantee a reasonable attenuation at resonance.
Because of the inter-resonator coupling, a minimum spacing between contiguous resonators is also restricted. It has been found that if the resonators are close to each other, inter-resonator coupling degrades sensor performance considerably.

The proposed strategy to solve the interresonator coupling problem has been to use an additional (fixed) resonant element on the stator (Fig. 3).

Companies specialized in magnetic sensors and measurements are sought for a license or a commercial agreement with technical cooperation from sectors such as aerospace and marine where robust equipment to withstand extreme environmental changes is needed but other applications for the technology are welcomed.
