Pulsed Schlieren Imaging of Ultrasonic Haptics and Levitation using Phased Arrays
Michele Iodice, William Frier, James Wilcox +2
Ultrasonic acoustic fields have recently been used to generate haptic effects on the human skin as well as to levitate small sub-wavelength size particles. Schlieren imaging and ba…
Connectivity of Underlay Cognitive Radio Networks with Directional Antennas
Qiu Wang, Hong-Ning Dai, Orestis Georgiou +2
In cognitive radio networks (CRNs), the connectivity of secondary users (SUs) is difficult to be guaranteed due to the existence of primary users (PUs). Most prior studies only con…
Spatial networks with wireless applications
Carl Dettmann, Orestis Georgiou, Pete Pratt
Many networks have nodes located in physical space, with links more common between closely spaced pairs of nodes. For example, the nodes could be wireless devices and links communi…
