A novel fluidic switch for high power applications

This work proposes a novel fluidic switch topology on coplanar waveguide transmission lines for high power applications. The bridge is created from a transverse fluidic network over the coplanar waveguide containing dispersions of spherical and high aspect ratio nanoparticles. In particular, the volume fraction of gold or silver nanoparticles dispersed into a low-dielectric oil to provide “on-off” switching states from the electrical conductivity of the fluid. First-order approximations for the fluids specific heat and thermal conductivity show good heat transfer properties for high power applications.
