Method and remotely adjustable reactive and resistive electrical elements |
摘要 |
Apparatus and method that includes providing a variable-parameter electrical component in a high-field environment and based on an electrical signal, automatically moving a movable portion of the electrical component in relation to another portion of the electrical component to vary at least one of its parameters. In some embodiments, the moving uses a mechanical movement device (e.g., a linear positioner, rotary motor, or pump). In some embodiments of the method, the electrical component has a variable inductance, capacitance, and/or resistance. Some embodiments include using a computer that controls the moving of the movable portion of the electrical component in order to vary an electrical parameter of the electrical component. Some embodiments include using a feedback signal to provide feedback control in order to adjust and/or maintain the electrical parameter. Some embodiments include a non-magnetic positioner connected to an electrical component configured to have its RLC parameters varied by the positioner. |

1. A method comprising:
providing an electrical component having a characteristic impedance at a first frequency; and based on an electrical feedback signal, automatically moving, using a non-magnetic mechanical-movement device, a movable portion of the electrical component in relation to another portion of the electrical component to change both the characteristic impedance and the first frequency. |
