Abstract
Orientation and position sensing methods and devices are disclosed. The described methods and devices are based on implementing magneto-electric-quasi-static fields for position and orientation sensing in lossy-dielectric, conducting, or metallic non-line-of-sight environments, where obstructions or occlusions or nearby objects exists that are lossy in nature and that typically perturb radio or electromagnetic wave signaling. Detailed experimental results highlighting the performance of the disclosed methods are also presented.

A non-line-of-sight system comprising:
- a transmitting device configured to transmit combined magneto-electric-quasi-static fields along one or more transmitting axes, the transmitting device further configured to transmit, through a non-line-of-sight environment including a lossy element, the magneto-electric-quasi-static fields in one or more frequency bands;
- and
- a receiving device configured to receive and detect the magneto-electric-quasi-static fields transmitted through the non-line-of sight-environment along one or more receiving axes,
- wherein:
- based on the detected magneto-electric-quasi-static fields, the system is configured to calculate an orientation-invariant range between the receiving device and the transmitting device,
- and the magneto-electric-quasi-static fields include a combination of separate electric-quasi-static fields and magneto-quasi-static fields.
