Frequency stabilisation in the Extremely High Frequency band. All precision communication and measurement systems (i.e. radar and navigation) rely on high quality oscillator technology. Any improvement in oscillator performance has a direct impact on the performance of the system and hence is of potential economic benefit. This project will realise the most stable frequencies ever produced in the underused Extremely High Frequency band, which is also important for space communications and naviga ....Frequency stabilisation in the Extremely High Frequency band. All precision communication and measurement systems (i.e. radar and navigation) rely on high quality oscillator technology. Any improvement in oscillator performance has a direct impact on the performance of the system and hence is of potential economic benefit. This project will realise the most stable frequencies ever produced in the underused Extremely High Frequency band, which is also important for space communications and navigation technology. System enhancement will include, better angular resolution, higher bandwidths, faster transmission rates and narrower beam widths without the susceptibility of absorption apparent from the optical domain.Read moreRead less
Microwave Frequency Standards: Testing Fundamental Physics and Developing New Devices. Highly frequency stable oscillators may be used as frequency or timing standards (clocks) and have commercial application as well as application of testing fundamental physical principles. This project is to continue the development of novel frequency standards in collaboration with some of the best research institutes in France funded by the French Space Agency (CNES).

Highly frequency stable oscillators may be used as frequency or timing standards (clocks) and have commercial application as well as application of testing fundamental physical principles. This project is to continue the development of novel frequency standards in collaboration with some of the best research institutes in France funded by the French Space Agency (CNES). With the advent of the International Space Station and new atomic clocks, the physics community is embarking on an experimental program that will make use of the microgravity environment of space. Combined with the new improved timing it will be possible to perform new experimental tests of general and special relativity, tests for drifts in the fine structure constant and tests for a preferred direction of the speed of light at unprecedented sensitivity.Read moreRead less

Investigation of spin excitations in ferromagnetic submicro- and nanostructures. The project will last 12 months and will be devoted to investigation of spin-wave dynamics in thin ferromagnetic-film sub-micro- and nano-structures for possible applications to microwave\millimetre wave electronic devices and to novel magnetic memory devices. Excitation of spin-wave modes in confined in magnetic nano- and submicro-objects (from the super-paramagnetic size limit up to 700 nm) will be theoreticall ....Investigation of spin excitations in ferromagnetic submicro- and nanostructures. The project will last 12 months and will be devoted to investigation of spin-wave dynamics in thin ferromagnetic-film sub-micro- and nano-structures for possible applications to microwave\millimetre wave electronic devices and to novel magnetic memory devices. Excitation of spin-wave modes in confined in magnetic nano- and submicro-objects (from the super-paramagnetic size limit up to 700 nm) will be theoretically studied. In co-operation with other research groups the obtained theoretical results will be experimentally verified. New information on microwave properties of the structures will be obtained. Possibility of application of the magnetic structures to construct new microwave devices will be considered.Read moreRead less
Techniques for probing biological media with holographic angular scattering spectroscopy. Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples. If depth selectivity can be added, we could perform non-invasive measurements on animals, making a huge re ....Techniques for probing biological media with holographic angular scattering spectroscopy. Huge effort in the biological and medical sciences is spent in using simple software to laboriously mark, count and measure cells and structures in microscope images of samples. We could replace this incredibly inefficient process in many instances with single-shot size-map images of unstained samples. If depth selectivity can be added, we could perform non-invasive measurements on animals, making a huge reduction in their usage. We could assess thick tissues enabling early noninvasive diagnosis of malignancy in tumours in situ or muscle characterization for meat quality or muscular dystrophy. These benefits impact on research, animal ethics, and on health, and have commercial potential in life and medical sciences, and the meat industry.Read moreRead less
