Bacterial inactivation using radial mode ultrasonic devices
… the bacterial inactivation capacity of radial and probe type ultrasonic horns. Radial horns were designed using finite element analysis and validated using experimental modal analysis. Several radial horns were investigated, tuned to the R0 and R3 modes, while probe type horns tuned to a …

Design of Radial Mode Piezoelectric Transformers for Lamp Ballast Applications
In the past, radial-mode piezoelectric transformer (Transoner) design has been difficult due to the complex interaction between the physical and electrical circuit characteristics. Prior to a design procedure, experimental design by Face Electronics, LC led to a sample that could fit a ballast …

Design of a Radial Mode Piezoelectric Transformer for a Charge Pump Electronic Ballast with High Power Factor and Zero Voltage Switching
… and the number of physical layers of the PT. A radial mode piezoelectric transformer prototype based on this design process was fabricated by Face Electronics Inc. and was tested experimentally, the results showed that the ballast using this custom-made PT achieved high power factor, …

A terahertz two-wire waveguide with low bending loss
… along a two-wire waveguide. We find that the mode pattern at the end of the waveguide resembles that of a dipole consistent, with the expected fundamental mode of the structure. We experimentally observe that the two-wire configuration can be used to efficiently excite the radial mode …

FUNDAMENTAL TECHNOLOGIES FOR THE OPTO MECHANICAL GYROSCOPE
… in a MEMS centric process flow. The mechanical modes were optically sensed with a tapered optical fiber coupled to a toroidal optical cavity fabricated on the lip of the hemispherical resonator. Next is the development of silicon opto-mechanical wineglass mode resonators with on-chip waveguides. …
