Latest Patents

Keji Lai holds a patent for "Modulated microwave microscopy and probes used therewith." This invention features a microwave microscope that includes a probe tip electrode, which is vertically positionable over a sample. The probe projects downwardly from the end of a cantilever, with a transmission line connecting the tip electrode to the electronic control system. This line extends along the cantilever and is separated from a ground plane by a dielectric layer. The probe tip can be vertically tapped near or at the sample surface at a low frequency, allowing for the demodulation of the microwave signal reflected from the tip/sample interaction. Additionally, a non-linear electrical element associated with the probe tip can interact with the applied microwave signal, enhancing the detection capabilities.
