This research investigates scattering of surface waves by obstacles among dielectric waveguides. The work embraces both theoretical and experimental studies of related scattering phenomena and is relevant to the study of guided-wave phenomena in both uniformly-clad and integrated surface-waveguide structures for millimeter and optical wavelengths. The methods are applicable as well to the scattering of waves along inherently simpler mm-wave microstrip-based circuits. An exact integral-operator description provides a new technique for the study of surface-wave scattering including mode conversion and radiation by dielectric obstacles having arbitrary shapes and refractive-index profiles. The analytical studies will be supported and guided by measurements at millimeter wavelengths using a complete- V-band millimeter-wave instrumentation setup.

本文研究了介质波导中障碍物对表面波的散射。本工作包括相关散射现象的理论和实验研究，并与毫米波和光学波长的均匀包覆和集成表面波导结构中的导波现象的研究有关。这些方法也适用于波沿着本身更简单的毫米波微带电路的散射。精确积分算子描述为研究具有任意形状和折射率分布的介质障碍物的表面波散射提供了一种新的方法，包括模式转换和辐射。分析研究将通过使用完整的v波段毫米波仪器设置的毫米波波长测量来支持和指导。
