This research is concerned with the application of gradient-index materials to complex optical systems. During the past few years, a number of design techniques and analytical tools for guided wave lenses were developed which are shown to be mathematically equivalent to gradient-index lenses in bulk form for wavelength dispersion, optical communication systems, propagation of water waves in the deep ocean for energy focusing, and the propagation of seismic waves in the earth's crust for oil exploration. The major areas to be studied include design and fabrication of gradient-index systems without rotational symmetry, an optical instrument for real-time measurement of the ion exchange process, and guided wave devices using principles of gradient-index optics. Also, measurement and characterization of gradient-index lenses operating at very high temperatures are being investigated.

这项研究涉及梯度折射率材料在复杂光学系统中的应用。 在过去的几年中，开发了许多导波透镜的设计技术和分析工具，这些技术和分析工具在数学上与用于波长色散、光通信系统、用于能量聚焦的深海中的水波传播以及用于石油勘探的地震波在地壳中的传播的散装形式的梯度折射率透镜等效。 研究的主要领域包括不具有旋转对称性的梯度折射率系统的设计和制造、用于实时测量离子交换过程的光学仪器以及利用梯度折射率光学原理的导波装置。 此外，正在研究在非常高的温度下工作的梯度折射率透镜的测量和表征。
