报告题目：Regularized Transformation-optics Cloaking

摘要: In this talk, I will describe the recent progress of our work on regularized transformation-optics cloaking. Ideal cloak makes use of singular metamaterials, posing great difficulties for both theoretical analysis and practical fabrication. Regularizations are incorporated into the construction to avoid the singular structures.
