A Harmonic Synchronized Oscillator using Gunn Diodes Embedded on Slot Line Resonators

This paper represents a novel second harmonic power combining oscillator using mutually synchronized Gunn diodes embedded on slot line resonators. A both-sided MIC technology is adopted in the oscillator. The oscillator consists of Gunn diodes, slot line resonators and microstrip lines. By embedding Gunn diodes on slot line resonators, desired harmonic RF signal can be generated very easily. Th...

Integration Techniques of pHEMTs and Planar Gunn Diodes on GaAs Substrates

This work presents two different approaches for the implementation of pseudomorphic high electron mobility transistors (pHEMTs) and planar Gunn diodes on the same gallium arsenide substrate. In the first approach, a combined wafer is used where a buffer layer separates the active layers of the two devices. A second approach was also examined using a single wafer where the AlGaAs/InGaAs/GaAs het...

Our study emphasises the need for additional, carefully designed studies when applying this potentially useful method in the search for genetic factors contributing to the aetiology of Parkinson's disease.tion between the oxidative polymorphism and early onset of Parkinson's disease.

Marcus Gunn phenomenon.

SINCE the jaw-winking phenomenon was first described by Marcus Gunn (1863), many such cases with other associated findings have been reported. Falls, Krause, and Cotterman (1949) reviewed 115 cases, Simpson (1956) published a comprehensive study, and Dhir and Agarwal (1961) reported a case following ptosis surgery. This case is reported because of an associated peculiarity which does not appear...
