Title: David Ethan Steinhauer: Innovator in Microwave Microscopy
Introduction
David Ethan Steinhauer is a notable inventor based in Laurel, MD (US). He has made significant contributions to the field of microwave microscopy, holding 2 patents that showcase his innovative approaches to sample analysis.
Latest Patents
One of his latest patents is titled "Disentangling sample topography and physical properties in scanning near-field microwave microscopy." This method involves using a calibration sample with variable properties to quantitatively measure two sample properties. By scanning the calibration sample and recording two measured variables, conversion functions are mathematically determined to convert these variables into the desired sample properties. This technique effectively eliminates the effects of topography on the computation of the second property of an unknown sample.
Another significant patent is for a "Near-field scanning microwave microscope having a transmission line." This microscope features a microwave generator connected to a mismatched transmission line that terminates in a probe. When a sample is brought close to the probe, the frequencies and quality factors of the standing wave resonances are modified. The reflected microwave signal varies based on the capacitance and conductivity of the sample, allowing for detailed imaging through relative scanning.
