Practical Model for Metamaterials in Wireless Power Transfer Systems
Metamaterials (MTMs) with extraordinary electromagnetic properties are recently applied to wireless power transfer (WPT) systems to improve power transmission efficiency. Although theoretical progress has been made on MTMs in low frequency near field, in

Novel Method to Improve the Signal to Noise Ratio in the Far-field Results Obtained from Planar Near Field Measurements. [PDF]
A method to reduce the noise power in far-field pattern without modifying the desired signal is proposed. Therefore, an important signal-to-noise ratio improvement may be achieved.

Near-field Nanoscopy of Terahertz Polaritons with Quantitative Dielectric Mapping [PDF]
Terahertz waves find broad use in physics, chemistry, and engineering for sensing applications. However, most experiments operate in the far-field, which precludes the observation of nanoscale features that affect the material response.

Vectorial near-field coupling [PDF]
The coherent exchange of optical near fields between two neighboring dipoles plays an essential role for the optical properties, quantum dynamics and thus for the function of many naturally occurring and artificial nanosystems. These interactions are inherently short-ranged, extending over a few nanometers only, and depend sensitively on relative ...
