Omnidirectional perfect acoustic cloak realized by homogeneous materials
Mohammad Hosein Fakheri, Hooman Barati sedeh, Ali Abdolali
Acoustic cloaks derived by coordinate transformation have opened up a new field of considerable interest in the last two decades. However, since perfect omnidirectional acoustic cl…
Non-Closed Acoustic Cloak Enabled by Sequential-Step Linear Coordinate Transformations
Zahra Basiri, Mohammad Hosein Fakheri, Ali Abdolali
Hitherto acoustic cloaking devices, which conceal objects externally, have depended on the objects' characteristics. Despite previous works, we design cloaking device placed neighb…
