Different geometries for spin-transfer oscillators

Several geometries have recently been proposed for spin-transfer oscillators, with the purpose of optimizing the output power and the frequency dependence on the applied current, as well as minimizing the external magnetic field required to stabilize magne ...

Realization of a solid-propellant based microthruster using low temperature co-fired ceramics

Peter Ryser, Thomas Maeder, Yannick Sébastien Fournier, Jaya Thakur

The introduction of micro-spacecrafts in the space industry has led to the development of various micro-propulsion techniques. Microthrusters are micropropulsion devices used in a microspacecraft for precise station keeping, orbit adjustment, attitude cont ...

Magnetic field sensor for measuring direction of a magnetic field in a plane

Radivoje Popovic, Pavel Kejik

A magnetic field sensor for measuring a direction of a magnetic field in a plane comprises a sensing structure (4) comprising a ring-shaped well (10), a plurality of contacts (11) of equal size placed at equal distance from each other along the ring-shaped ...
