Applied Electromagnetics and Advanced Antennas

我提出的研究的目标是利用电磁原理开发数学工具来研究波与周围介质的相互作用，并使电磁设备的设计成为可能，例如天线、传感器和其他组件，用于科学和工程新兴领域的应用。它将在通信和遥感方面取得几项突破性进展。 我将对低损耗工程材料的发展进行研究。在无线电科学和任何与电磁波有关的事物中，导体损耗一直是“万恶之源”，并创造了超导的梦想。最近，我以一种适度的方式展示了分层结构的减损，本研究将利用物理原理对其进行详细的研究，并建立数学模型以使其最小化。导电降损将在多个科技领域掀起新一轮创新浪潮。 我建议借助电磁建模和信号处理技术，推进虚拟天线阵的研究，即用一根天线代替多根天线。随着进一步的发展，我打算研究它在合成孔径雷达和卫星观测中的应用，使用高增益天线。我还将研究设备小型化通过硬件最小化或用软件取代而产生变革性影响的应用程序。 我计划进一步研究北极海冰的电磁响应，并开发专门的算法来根据其特殊特征进行散射，如霜花和卤水包裹体。这项研究的结果将对增进我们对海冰的了解，以及通过大规模卫星观测进行预测，以及北方的可持续发展将是非常宝贵的。 我建议研究物体和组织异常散射的电磁波的对称特性。这项研究将把接收到的响应与物体的位置联系起来，而不是目前微波成像中使用的源对比度。它的特征将类似于MRI成像，后者的信号处理可以用于提高异常的检测和识别。

The objective of my proposed research is to use electromagnetic principles for developing mathematical tools for investigating the wave interactions with surrounding media, and to enable the design of electromagnetic devices, such as antennas, sensors, and other components for applications in emerging areas in science and engineering. It will have several groundbreaking advances in communication and remote sensing. I will conduct research on the development of low loss engineered materials. The conductor losses have been “the source of all evil” in radio science and anything dealing with electromagnetic waves, and created the dream of superconductivity. Recently, in a modest way, I have demonstrated loss reduction in layered structures, and this research will investigate it in detail, using physical principles, and develop mathematical models for its minimization. Conductive loss reduction will launch a new wave of innovation in many areas of science and technology. I propose to advance my research on virtual antenna arrays, which replaces multiple antennas with only one, with the aid of electromagnetic modeling and signal processing. With further development, I intend to investigate its applications in synthetic aperture radars and satellite observations, using high gain antennas. I will also study applications where device miniaturization has a transformative impact, by hardware minimization, or replacement with software. I plan to further study the electromagnetic response of Arctic sea ice, and develop dedicated algorithms for scattering by its special features, such as frost flowers and brine inclusions. The results of this research will be invaluable for improving our understanding of the sea ice, and predictions by large-scale satellite observations, and sustainable development of the North. I propose investigating the symmetric properties of electromagnetic waves scattered from objects and tissue anomalies. This research will relate the received response to the object’s location, rather than the source contrast, used currently in microwave imaging. Its features will be similar to MRI imaging and the latter’s signal processing can be used to improve the detection and identification of the anomalies.
