Improvements to the electromagnetically launched expanding ring experiment that make the technique more reproducible, analyzable, and amenable to the rapid testing of many specimens are presented. Aspects of the design and containment of the primary solenoid, high-voltage switching, and...
- Reflectivity of planar metallic fractal patterns. Zhou, Lei; Wen, Weijia; Chan, C. T.; Sheng, Ping // Applied Physics Letters;2/17/2003, Vol. 82 Issue 7, p1012
We studied the reflective properties of a small dielectric plate covered with a fractal-like metallic pattern generated by a particular type of space-filling curves. We found, both experimentally and theoretically, that the plate can reflect electromagnetic waves in a multitude of frequencies,...
