Description:

This course presents a comprehensive exploration of mathematical theories on metamaterials within wave systems including acoustics, electromagnetics, and elasticity. The analytical methodologies encompass both the potential theory and the variational approach. Subsequently, the course delves into the practical applications including cloaking invisibility and imaging. Regarding invisibility, we mainly focus on the exceptional phenomenon known as cloaking due to anomalous localized resonance. At last, the mathematical theory on the fabrication of the metamaterial shall be introduced.

Prerequisite:

partial differential equation, potential theory, Sobolev space
