Abstract

A tunable nanomechanical resonator system comprising an array of nanofeatures, such as nanotubes, where the nanofeatures are in signal communication with means for inducing a difference in charge density in the nanofeature such that the mechanical resonant frequency of the nanofeature can be tuned, and where the nanofeature is in signal communication with a waveguide or other RF bias conduit such that an RF signal having a frequency corresponding to the mechanical resonant frequency of the array will couple to the array thereby inducing resonant motion in the array of nanofeatures, and subsequently coupling to an output waveguide, forming a nanoscale RF filter is provided. A method of producing a nanoscale RF filter structure controllably positioned and oriented with a waveguide and integrated electrodes is also provided.
