Novel microwave near-field sensors for material characterization, biology, and nanotechnology
摘要：
当代材料有趣的电磁行为的广泛范围要求在这个领域工作的实验人员掌握许多不同的测量技术，并对凝聚态物理和生物物理学有广泛的了解。测量材料在微波频率下的电磁响应对于基本和实际原因都是重要的。在本文中，我们提出了一种新的近场微波传感器与应用材料表征，生物学和纳米技术。该传感器是基于一个亚波长铁氧体磁盘谐振器与磁偶极模式（MDM）振荡。MDM谐振器产生的近场的强能量集中和独特的拓扑结构允许有效地测量微波中的材料参数，无论是普通结构还是具有手性特性的物体。
英文摘要：
The wide range of interesting electromagnetic behavior of contemporary materials requires that experimentalists working in this field master many diverse measurement techniques and have a broad understanding of condensed matter physics and biophysics. Measurement of the electromagnetic response of materials at microwave frequencies is important for both fundamental and practical reasons. In this paper, we propose a novel near-field microwave sensor with application to material characterization, biology, and nanotechnology. The sensor is based on a subwavelength ferrite-disk resonator with magnetic-dipolar-mode (MDM) oscillations. Strong energy concentration and unique topological structures of the near fields originated from the MDM resonators allow effective measuring material parameters in microwaves, both for ordinary structures and objects with chiral properties.
