Near-field focusing using phased arrays with dynamic polarization control
Nitin Jonathan Myers, Yanki Aslan, Geethu Joseph
Phased arrays in near-field communication allow the transmitter to focus wireless signals in a small region around the receiver. Proper focusing is achieved by carefully tuning the…

Temporal Detection of Anomalies via Actor-Critic Based Controlled Sensing
Geethu Joseph, M. Cenk Gursoy, Pramod K. Varshney
We address the problem of monitoring a set of binary stochastic processes and generating an alert when the number of anomalies among them exceeds a threshold. For this, the decisio…
