It was an action packed programme with key note and student presentations, followed by Q&A sessions by the review panel, concluding with an awarding ceremony for the best presentation prize.
The presentations were first class and generated lots of discussion from the attendees at the event. It provided a unique speaking opportunity to young engineers who have limited experience in presenting at a professional seminar in a supportive environment.
There is also a seminar digest available for download, containing the following presentations and abstracts.
Microwave processing is an expensive form of power used to deliver transformational economics enabling butter tempering, bacon cooking, rubber vulcanisation and artificial diamonds.
We describe a Near-field Scanning Microwave Microscope (NSMM) which images the complex permittivity of materials at a micron scales, and also allows traceable measurements at particular locations to be made at an increased level of precision.
Until recently, the lack of the basic building blocks (sources, detectors optical feeds and measurement tools) in the so called ‘Terahertz Gap’ has severely limited any thought of heating of materials or industrial processing except with the use of high power Gyrotrons. These can output 10 100’s of kilowatts in the millimetre wave region but they are complex and highly specialised.
In the biomass action plan of 2005, the EU sets a target of 150 million tonnes of oil equivalent to be derived from biomass by 2020 to reduce dependence on foreign energy and to help meet obligations under the Kyoto agreement.
Finding a renewable source of energy to replace fossil fuels has been the focus of many research activities around the world. Generation of hydrogen through phototelectrochemcial (PEC) water splitting, also known as solar-driven water splitting is one of the most promising alternatives for the production of hydrogen as a fuel.
This paper presents a 2.45 GHz microwave cavity resonator with the novel dual function of both sensitive dielectric characterisation and directed, volumetric heating of fluids in a microfluidic chip. This method has a higher efficiency, higher rate of heating and is more controllable than previous microfluidic microwave heating methods.
Offshore drilling yields a variety of oily wastes, which need to be treated and disposed of. Oil contaminated drill cuttings are rock fragments impregnated with oil and can be considered to have three distinct main phases the rock, the oil and water.
The application of high-frequency resonant transformers in the transmission of power has been described in the literature, but as yet there has been no direct effort to quantify and map the near-field of such electrically small RF structures. This curiosity lead research investigated the feasibility to distribute power using quasi-static fields.
The depletion of conventional fossil-fuels and the increase in crude oil prices has resulted in the search for alternative energy sources. Civilisation’s reliance on petroleum and its by-products is so embedded that transforming world economies to renewable energy derived systems is still a distant prospect.
Conventional synthesis of solid state materials is time and energy intensive, often requiring extremely high temperatures and complicated experimental procedures. Microwave (MW) synthesis is emerging as a viable alternative.
The basic design of the open-ended single mode resonant applicator as shown in Figure 1 (see abstract for figure) creates a resonance within the dielectric block, whilst the fields in the air filled section are below cutoff and therefore evanescent.
