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.

这个研究计划解决电磁反演。电磁反演是指利用外部电磁观测资料，反演研究区域的某些性质的过程。这一过程涉及电磁数据收集技术和解释算法。我们将开发新的电磁反演算法和技术，以影响三个应用领域：微波层析成像，近场天线测量和天线优化。所提出的研究的新颖性在于我们（1）解释所收集的电磁数据（2）增加所收集的电磁数据的信息内容，以及（3）有利地利用电磁反演进行天线优化和测量。 使用新的反演算法和技术，我们将提高图像的定量精度和分辨率可从微波层析成像。这项研究引起了加拿大人的高度兴趣，因为微波断层扫描作为一种新兴的成像方式，有很大的希望影响几种生物医学成像应用（例如，乳腺癌检测/识别）。我们还将使用新的反演算法结合近场天线测量，以实现更准确的远场和近场天线表征。我们将介绍一种新的电磁散射公式天线优化，这可能会打开天线优化的新的可能性。拟议的近场天线测量和天线优化研究对加拿大保持在天体和地球通信的前沿非常重要。该研究计划在马尼托巴大学现有的天线实验室和电磁成像实验室进行，将培训电磁成像，近场天线测量和优化方面的高素质人员。这些高度合格的人员将有助于加拿大各组织寻找这些领域的专家。
