Dynamically reconfigurable bandpass filters
First Claim
1. A dynamically reconfigurable bandpass filter comprising:
- a resonator loop; and
a microfluidic channel proximate to the resonator loop, the channel containing a conductor, wherein the position of the conductor within the channel can be adjusted to change capacitive loading of the resonator loop and therefore change the frequencies that the filter passes.

Abstract
In one embodiment, a dynamically reconfigurable bandpass filter includes a resonator loop and a microfluidic channel proximate to the resonator loop, the channel containing a conductor, wherein the position of the conductor within the channel can be adjusted to change capacitive loading of the resonator loop and therefore change the frequencies that the filter passes. In another embodiment, a filter includes a second resonator loop having comprising switches located at discrete positions along a length of the second resonator loop, wherein opening and closing of the switches changes the effective length of the second resonator loop to change capacitive loading of the first resonator loop.
