제목:  Acoustic Metamaterials and Reversal of Sound

 

연사: 김   철   구 교수님 (연세대학교 물리학과)

 

일시: 2011년 10월 5일(수) 오후 4:30

 

장소: e+첨단강의실 (31214호실)

 

초록:  Is it possible to have materials with negative mass and negative bulk modulus?

The answer is Yes. We have fabricated acoustic metamaterials with negative mass and negative bulk modulus. In these materials, sound travels backwards and many seemingly impossible phenomena, such as acoustic cloaking and superlensing can be realized.
