Abstract

Nanomaterial characterization using microwaves is needed in nanoscale semiconductor devices, microwave imaging, EM shielding, and wireless communication. Many nanomaterials are used as metallic or dielectric layers in these applications. In this paper, we report the characterization of nanomaterials using planar Microwave Slot Resonator (MSR) which was designed and studied using 3D EM simulation tool. The response of MSR is parameterized which offers a platform to calculate relative permittivity (ε r) and conductivity (σ) from measured high frequency response of nanomaterial loaded MSR. With simplified method, this microwave characterization offers accurate and faster results which be used in design, calculation and numerical analysis of nanomaterial based electronic/optoelectronic devices and sensor/shielding applications.

利用平面槽谐振器对纳米材料进行微波表征

在纳米级半导体器件、微波成像、电磁屏蔽和无线通信中需要使用微波对纳米材料进行表征。在这些应用中，许多纳米材料被用作金属层或电介质层。本文报告了使用平面微波狭槽谐振器（MSR）对纳米材料进行表征的情况，该谐振器是使用三维电磁模拟工具设计和研究的。对 MSR 的响应进行了参数化处理，从而提供了一个平台，可根据测量到的加载 MSR 的纳米材料高频响应计算相对介电常数 (ε r) 和电导率 (σ)。通过简化方法，该微波表征方法可提供准确、快速的结果，用于基于纳米材料的电子/光电器件和传感器/屏蔽应用的设计、计算和数值分析。

期刊介绍： Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance. Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
