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…

Anomaly Detection Under Controlled Sensing Using Actor-Critic Reinforcement Learning
Geethu Joseph, M. Cenk Gursoy, Pramod K. Varshney
We consider the problem of detecting anomalies among a given set of processes using their noisy binary sensor measurements. The noiseless sensor measurement corresponding to a norm…

Measurement Bounds for Compressed Sensing in Sensor Networks with Missing Data
Geethu Joseph, Pramod K. Varshney
In this paper, we study the problem of sparse vector recovery at the fusion center of a sensor network from linear sensor measurements when there is missing data. In the presence o…
