Power Aware Placement of On-Chip Voltage Regulators

Rassul Bairamkulov

In traditional power delivery networks, the on-chip supply voltage is provided by board-level converters. Due to the significant distance between the converter and the load, variations in the load current are not effectively managed, producing a significan ...

A Closed Time-Reversal Cavity for Electromagnetic Waves in Transmission Line Networks

Mario Paolone, Marcos Rubinstein, Zhaoyang Wang, Reza Razzaghi

A closed time-reversal (TR) cavity has been considered a purely theoretical concept whose experimental realization was assumed to be impossible. In this article, we demonstrate that it is, in fact, possible to realize a closed TR cavity using a network of ...

Properties of convex optimal power flow model based on power loss relaxation

Mario Paolone, Zhao Yuan

We derive the branch ampacity constraint associated to power losses for the convex optimal power flow (OPF) model based on the branch flow formulation. The branch ampacity constraint derivation is motivated by the physical interpretation of the transmissio ...
