Title: Innovations of Robert L. Miller
Introduction
Robert L. Miller is a notable inventor based in Schaumburg, IL (US), recognized for his contributions to the field of surface acoustic wave devices. With a total of two patents to his name, Miller has made significant advancements in technology that enhance the functionality of electronic devices.
Latest Patents
Miller's latest patents include a "Surface Acoustic Wave Device Employing Reflectors" and a "Surface Wave Device with Suppressed Boundary-Reflected Waves." The first patent describes a device where electric domain reversals are arranged in parallel arrays on a piezoelectric ceramic substrate. This configuration forms strong reflectors of surface acoustic waves, which are essential in devices such as filters and resonators. The domains are created through a poling process that utilizes a selective electrode pattern and a high DC voltage applied at a temperature above ambient but below the Curie temperature of the substrate.
The second patent outlines a surface wave transmitting device that features a piezoelectric surface wave propagative medium along with interdigitated comb-type input and output transducers. The input transducer is designed to respond to a source of input signals, launching surface waves of a predetermined center wavelength. The output transducer receives these surface waves and generates output signals. This device is enhanced by the arrangement of the transducers, which allows for the cancellation of spurious surface waves, improving overall performance.
