Acoustic imaging by three-dimensional acoustic Luneburg meta-lens with lattice columns
Jung-Woo Kim, Seong-Jin Lee, Jun-Yeong Jo +2
A three-dimensional acoustic Luneburg meta-lens has the advantage of refracting sound waves for all incident angles and focusing higher sound pressure compared to a two-dimensional…
Sound Reception System by an Acoustic Luneburg Lens
Sang-Hoon Kim, Byeong-Won, Kyung-Min +1
Applying the directionality of a Luneburg lens, a sound reception system for ships is designed. A two-dimensional acoustic Luneburg lens which is made of 253 acrylic pipes of diffe…
Seismic Negative Belt of Acoustic Metamaterials
Sang-Hoon Kim, Mukunda P. Das
An earthquake-proof seismic negative belt of an artificial seismic shadow zone is introduced. The belt is composed of acoustic materials which has one of the constituent parameter…
Acoustic Eaton lens array and its fluid application
Sang-Hoon Kim, Sy Pham-Van, Mukunda P. Das
A principle of an acoustic Eaton Lens array and its application as a removable tsunami wall is proposed theoretically. The lenses are made of expandable rubber pillars or balloons…
Comments on "Thermally induced rotons in two-dimensional dilute Bose gases" [arXiv:cond-mat/0503523]
Sang-Hoon Kim
A mistake of the effective interaction between D-dimensional Bose atoms [arXiv:cond-mat/0503523] that was published by Physical Review B in 2006 is corrected.
First-order quantum correction to the ground-state energy density of two-dimensional hard-sphere Bose atoms
Sang-Hoon Kim, Mukunda P. Das
Divergence exponents of the first-order quantum correction of a two-dimensional hard-sphere Bose atoms are obtained by an effective field theory method. The first-order correction…
