Engineering Research Equipment Grant: Equipment for RF Measurements

这项工程研究设备拨款用于购买网络分析系统（惠普8510B），以支持密西西比大学电气工程系目前在三个具体项目上的研究，并将由所有员工使用，以扩大其研究活动的范围和质量。由于现有设备已经过时，需要提高测量精度，以便通过测量进行验证，因此对所提出的网络分析仪系统的要求已经成为行业标准。目前，对EM边值问题的解析和数值解的研究已经过时。该设备将促进以下特定领域的研究：1)用于测量材料特性的空腔法——一项提高介电常数和表面电导率测量精度和误差估计的研究；2)嵌入有损介质中的天线——一项向空气有损介质界面倾斜的导线的实验研究，以验证一个著名的数值分析程序。3)介质辐射元件——微波和毫米波应用的非金属辐射元件的研究。相关网络分析仪测量的辅助用途是在新的天线馈电技术、相控阵和使用矩形波导中电介质的共振方法进行腔体测量等领域。

This Engineering Research Equipment Grant is for the purchase of a network analyzer system (Hewlett Packard 8510B) to support current research by the Department of Electrical Engineering at the University of Mississippi on three specific projects, and it will be used by all the staff to broaden the scope and quality of their research activities. The requirement for the proposed network analyzer system, which has already become an industry standard, has been necessitated by the need to improve measurement accuracy required for verification through measurements related current research on analytic and numerical solution of EM boundary-value problems, because existing equipment is obsolete. The equipment will facilitate research in the specific areas of 1) cavity method for measurement of material properties - an investigation to improve accuracy and error estimates in measurements of dielectric constant and surface conductivity, 2) antennas embedded in lossy media - an experimental study of wires inclined to an air-lossy media interface to verify a well-known numerical analysis program, and 3) dielectric radiating elements - an investigation of non-metallic radiating elements for microwave and millimeter wave applications. Auxiliary uses for related network analyzer measurements are in the areas of new antenna feeding techniques, phased arrays, and cavity measurements using the resonance method for dielectric in rectangular waveguide.
