Title: Ulrich Busk Hoff and Density-Modulated Phononic Membranes

Introduction

Ulrich Busk Hoff is an inventor associated with Kongens Lyngby, Denmark. His work includes a patent for a mechanical oscillator design that uses a phononic membrane to control mechanical vibrations.

Latest Patents

Hoff is associated with 1 patent: “Density-modulated phononic membranes.” The invention describes an unsupported membrane containing discrete mass elements arranged into phononic crystal cells. A defect in the crystal structure confines a mechanical oscillation mode, while the mass elements are smaller than one-tenth of the mode’s wavelength.

The design creates a periodic density-contrast pattern that produces a bandgap while maintaining uniform tensile stress. This alignment between the stress distribution and the mode shape can reduce damping and support high mechanical quality factors.

Career Highlights

Hoff is associated with Danmarks Tekniske Universitet, also known in English as the Technical University of Denmark. The available information identifies his work in connection with research on phononic membranes and mechanical oscillators.

Collaborations

His listed coworkers include Dennis Høj and Ulrik Lund Andersen. Their shared research context includes the development of density-modulated phononic membrane technology.

Conclusion

Ulrich Busk Hoff’s patent presents a membrane-based approach to confining mechanical oscillations, with a design intended to reduce damping and enable high quality factors.
