In today's smart world, the Internet of Things (IoT) offers a very large scale technologies and use cases. An IoT system comprises huge amount low-power network elements, sensors, devices connected to each other. For these devices, it is important have sufficient level energy resource for communication receive software/firmware updates periodically. this aspect, wireless power transfer popular ...

A new coordinate system is proposed for the purposes of analysis far-field radiation from a localized source at origin. The stereographic coordinates exhibit no singularities over hemisphere, making them good choice automated pattern analysis. Finally, it shown that Ludwig polarization basis, commonly used to represent radiation, arises naturally, as basis when one uses coordinates.
