摘要： Radio frequency (RF) switch comprising an electromagnet formed on a magnet, a transmission line formed on the electromagnet and having a ground line and a signal line, and a movable contact connected to either the ground line or the signal line and capable of electrically coupling the ground line with the signal line. The transmission line is capable of propagating a RF signal if the ground line is electrically decoupled from the signal line. Conversely, the transmission line is incapable of propagating a RF signal if the ground line is electrically coupled with the signal line. The electromagnet can comprise an electromagnetic coil, formed in a layer of dielectric material, electrically coupled to a current source. Preferably, the movable contact is capable of being magnetically actuated, and is latchable. The magnet, the electromagnet, the transmission line, and the movable contact can have dimensions at a micron order of magnitude. The transmission line can be a coplanar waveguide. The coplanar waveguide can include a ground plane positioned between a layer of dielectric material and the electromagnet. The coplanar waveguide can also include means to electrically couple the ground plane to the ground line.

摘要： A micro-magnetic switch includes a permanent magnet and a supporting device having contacts coupled thereto and an embedded coil. The supporting device can be positioned proximate to the magnet. The switch also includes a cantilever coupled at a central point to the supporting device. The cantilever has a conducting material coupled proximate an end and on a side of the cantilever facing the supporting device and having a soft magnetic material coupled thereto. During thermal cycling the cantilever can freely expand based on being coupled at a central point to the supporting device, which substantially reduces coefficient of thermal expansion differences between the cantilever and the supporting device.

摘要： A micro-machined magnetic latching switch is described. A moveable micro-machined cantilever has a magnetic material and a longitudinal axis. The cantilever has a conducting layer. A permanent magnet produces a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the longitudinal axis of the cantilever. The first magnetic field is approximately perpendicular to longitudinal axis. A three-dimensional solenoid coil produces a second magnetic field to switch the cantilever between a first stable state and a second stable state. The temporary current is input to the three-dimensional solenoid coil, producing the second magnetic field such that a component of the second magnetic field parallel to the longitudinal axis changes direction of the magnetization vector. The cantilever is thereby caused to switch between the first stable state and the second stable state.

摘要： A micro magnetic switch includes a reference plane and a magnet located proximate to a supporting structure. The magnet produces a first magnetic field with uniformly spaced field lines approximately orthogonal to the reference plane, symmetrically spaced about a central axis, or non-uniformly spaced fields approximately orthogonal to the reference plane. The switch also includes a cantilever supported by the support structure. The cantilever has an axis of rotation lying in the reference plane and has magnetic material that makes the cantilever sensitive to the first magnetic field, such that the cantilever is configured to rotate about the axis of rotation between first and second states. The switch further includes a conductor located proximate to the supporting structure and the cantilever. The conductor is configured to conduct a current. The current produces a second magnetic field having a component approximately parallel to the reference plane and approximately perpendicular to the rotational axis of the cantilever, which causes the cantilever to switch between the first and second states. The switch still further includes a stopping device located proximate to the supporting structure. The stopping device is operable to stop the cantilever from rotating about the axis of symmetry beyond a point at which a longitudinal axis of the cantilever is approximately parallel to a longitudinal axis of the magnet.

摘要： A micro magnetic latching device. The device comprises a substrate having a moveable element supported thereon. The moveable element (cantilever) has a long axis and a magnetic material. The device also has first and second magnets that produce a first magnetic field, which induces a magnetization in the magnetic material. The magnetization is characterized by a magnetization vector pointing in a direction along the long axis of the moveable element, wherein the first magnetic field is approximately perpendicular to a major central portion of the long axis. The device also has a coil that produces a second magnetic field to switch the movable element between two stable states, wherein only temporary application of the second magnetic field is required to change direction of the magnetization vector thereby causing the movable element to switch between the two stable states.
