A square complex matrix A is EP if it satisfies (or, equivalently, ). This paper aims to introduce two natural generalizations of EP matrices: a square matrix A is defined to be left or right power-EP if it satisfies or for some integer , respectively. Some properties, characterizations ...

This device has composite right/left-hand property, similar to the right/left-hand metamaterials. Its nonlinear effects on temperature and power are studied by theoretical analysis and experiments. In this work, a circuit model is built to describe and interpret the performance of this device. ...
