Sandwich panel design and performance optimization based on triply periodic minimal surfaces

Computer-Aided Design, 2019
Abstract Sandwich panel is a promising engineering structure, attracting more and more research attention. Most of current sandwich panels are constructed with plane skins and lattice cores via traditional fabrication processes. In this work, the skin faces of sandwich panels are designed by the freeform T-spline surfaces. The triply periodic minimal

Optimization of three- and four-element lens systems by minimizing the caustic surfaces

Applied Optics, 1990
For an imaging optical system it is, in general, desirable to transform a collection of point sources of light into point images distributed over the focal plane with the appropriate magnification. In practice, this is achieved by varying the lens system parameters such that the spread of a bundle of rays from each object point over the image plane has
