Exceeding the Classical Time-bandwidth Product in Nonlinear Time-invariant Systems
Alireza Mojahed, Kosmas L. Tsakmakidis, Lawrence A. Bergman +1
The classical 'time-bandwidth' limit for linear time-invariant (LTI) devices asserts that it is impossible to store broadband waves (large Δω's) for long times (large Δt's). For st…

Acoustic Steering of Active Spherical Carriers
Majid Rajabi, Hossein Khodavirdi, Alireza Mojahed
Following the novel introduced concept of the active carriers, this paper brings forward a technique toward the manipulability of an internally piezo-equipped active spherical carr…
