"Enhanced Electromagnetic Inversion: Algorithms, Techniques, and Emerging Applications"

点击翻译按钮获取中文摘要

This research program addresses electromagnetic inversion. Electromagnetic inversion is defined as the process by which some properties of an investigation domain are inferred from outer electromagnetic observations. This process involves electromagnetic data collection techniques and interpretation algorithms. We will develop novel electromagnetic inversion algorithms and techniques to impact three application areas: microwave tomography, near-field antenna measurements, and antenna optimization. The novelties of the proposed research lie in the ways that we (1) interpret the collected electromagnetic data (2) increase the information content of the collected electromagnetic data, and (3) advantageously utilize electromagnetic inversion for antenna optimization and measurements. Using novel inversion algorithms and techniques, we will enhance the image quantitative accuracy and resolution obtainable from microwave tomography. This research is of high interest to Canadians because microwave tomography, as an emerging imaging modality, holds great promise to impact several biomedical imaging applications (e.g., breast cancer detection/identification). We will also use novel inversion algorithms in conjunction with near-field antenna measurements to achieve more accurate far-field and near-field antenna characterization. We will introduce a novel electromagnetic scattering formulation for antenna optimization, which could open up new possibilities for antenna optimization. The proposed research in both near-field antenna measurements and antenna optimization are very important to Canada to remain at the forefront of both celestial and earthly communications. This research program, which takes place in the existing Antenna Lab and Electromagnetic Imaging Lab at the University of Manitoba, will train highly qualified personnel in electromagnetic imaging, near-field antenna measurements and optimization. These highly qualified personnel will contribute to the Canadian organizations seeking experts in these areas.
