Abstract
Systems, tools, and methods for measurement of a property of a solid body or fluid involve an electromagnetic measurement tool that includes a transmitter configured to transmit electromagnetic energy, a receiver configured to receive the electromagnetic energy, and a metamaterial element comprising a negative refractive index. The metamaterial element may focus the electromagnetic energy. The electromagnetic tool may be placed adjacent the solid body or fluid, electromagnetic energy may be transmitted via the transmitter, and the electromagnetic energy may be received with the receiver to measure a property of the solid body or fluid.
