... Abstract Liquid viscosity is an important quantity for medical analyses (accurate and fast one-time tests) and microfluidic reaction systems (continuous flow sensing). A novel integrated piezoelectric layer with a polymer waveguide on a quartz SH-SAW device has been developed for liquid sensing...

... materials are processed in rectangular sections of waveguide fed by a magnetron with a maximum output power of 2 kW operating at 2.45 GHz. The most significant problems encountered when processing these materials are: (i) maintaining proper tuning to ensure maximum power transfer, (ii) thermal runaway...

... to external conditions has yet to be developed. To advance the state of the art, this research proposes a tunable 3D elastic metamaterial that enables the reconfiguration of a topological waveguide through the switching of metastable states. Through careful design of internal bistable elements...
