Tobón, L. (author), Chen, J. (author), Lee, J. (author), Yuan, M. (author), Zhao, B. (author), Liu, Q.H. (author)Many system-level electromagnetic design problems are multiscale and very challenging to solve. They remain a significant barrier to system design optimization for a foreseeable future. Such multiscale problems often contain three electrical scales, i.e., the fine scale (geometrical feature size much smaller than a wavelength), the coarse scale ...conference paper 2013
