Electronically tuned 23 GHz Gunn oscillators for a microwave datalink
No full textIncludes bibliographical references.A market has been identified for 23 GHz, short-haul, low-capacity, digital radio. The dissertation presents the development of the varactor controlled Gunn oscillators that constitute the crystal locked microwave sources of the radio. An accurate description of a design procedure for Gunn oscillators at 23 GHz is presented. With reference to advanced modulation methods which require constant modulation indices, a method of linearising the voltage/frequency characteristic of the varactor controlled Gunn oscillator is described, which allows direct modulation of the source at 23 GHz. Due to the wide operating temperature of the radio a technique to temperature compensate the oscillator is presented. The dissertation ends with an investigation how the semiconductor device's spread affects the oscillator characteristics and an evaluation of the noise performance of the Gunn oscillator
Thom Gunn papers
No full textThom Gunn (1929-2004) was a British poet, whose residence was primarily the United States beginning in the 1950s. He published over thirty books of poetry, a collection of essays, and four edited collections. His work is widely represented in literary anthologies. Gunn combined an interest in traditional poetics with less traditional subjects, such as Hell's Angels, LSD, and homosexuality. The collection includes drafts, notebooks, publications, correspondence, and photographs. The bulk of the collection includes materials from his books Positives (1966) and Touch (1967)
Planar gunn diode characterisation and resonators elements to realise oscillator circuits
No full textThe paper describes the planar Gunn diode, which is well suited to providing milli-metric and tera hertz sources using microwave monolithic integrated circuit (MMIC) technologies. Different planar Gunn electrode geometries are described along with DC, RF and thermal characterisation. To realize the planar high frequency sources there is requirement for high frequency planar resonators, the paper will describe both the radial and new diamond shaped geometries
Gunn Collection
No full textProfessor Emeritus Drewey Wayne Gunn served as an active Texas A&M University-Kingsville University faculty member from 1968 to the present (except for a sojourn in Denmark as a Fulbright teacher and in France as an ESL teacher from 1972 to 1977). He is a literary historian, editor, translator and author. Dr. Gunn donated a collection of Tennessee Williams literature. It includes articles, maps, and plays featuring literature he loves and a field he enhanced with his publications and work
Jeannie Gunn
No full textJeannie met her husband Aeneas James Gunn in Melbourne they were married on 31 December 1901. At that time he was a partner in Elsey cattle station on the Roper River, some 300 miles (483 km) south of Darwin. In January 1902 the newly married coupled sailed to Port Darwin so James could start his new position as Station Manager at the Elsey cattle station. After 13 months Aeneas died of malarial dysentery and Jeannie returned Melbourne to live with her father in Hawthorn and never returned to the Northern Territory.
Although her time was relatively short in the Northern Territory friends encouraged Jeannie to write about her experiences, because of the stories she told and letters she had sent to them about life on the station. Over the next few years she wrote two books titled 'The Little Black Princess: a True Tale of life in the Never-Never Land' published in 1905 and 'We of the Never-Never' published in 1908. By 1931 she was famous and ranked third among Australian novelists. Her books have been adapted for schools and were translated into German in the 1920s. By 1990 over 1 million copies of 'We of the Never Never' had been sold. Jeannie Gunn's books are Australian Classics and have been read and cherished for generations. Mrs Aeneas Gunn passed away on 9 June 1961 four days after celebrating her 91st birthday.Author

A planar Gunn diode operating above 100 GHz
No full textWe show the experimental realization of a 108-GHz planar Gunn diode structure fabricated in GaAs/AlGaAs. There is a considerable interest in such devices since they lend themselves to integration into millimeter-wave and terahertz integrated circuits. The material used was grown by molecular beam epitaxy, and devices were made using electron beam lithography. Since the frequency of oscillation is defined by the lithographically controlled anode-cathode distance, the technology shows great promise in fabricating single chip terahertz sources

Landscape to light: selected essays by Neil M Gunn.
No full textAlthough Neil M. Gunn is well-known as one of Scotland's foremost writers of the 20th century, he is less well-known as a perceptive and meditative essayist who wrote on a variety of subjects - from landscape, nature and the sea to literature, politics and matters of the spirit. Written in parallel with his novels, these essays contain many of the ideas and speculations that inform them. In this collection the focus is on landscape and the stimulus it provides for a journey of an enquiring mind from the observation of everyday life to a state of self-realisation. The essays mark the route. For example, in The French Fishing Smack there is a sense of freedom that only the sea can give; in The First Salmon a primal sense of adventure captivates; The Heron's Legs cannot but engender a sense of wonder and Light is a signal that the inner journey of the spirit has all but ended
