They are electromagnetic: they result from oscillations of the electromagnetic field and don't need a physical medium. So they, like other types of electromagnetic wave, can travel basically anywhere—through a vacuum or through atmosphere or water.Now, radio waves can be detected. For example, ...
They result from oscillations of the electromagnetic field and don't need a physical medium, so they, like other types of electromagnetic wave, can travel basically anywhere, through a vacuum, or through atmosphere or water. Now, radio waves can be detected. For example, very low frequency rad...
This device demonstrates that the functionalities of two metasurfaces may be exploited in a single design if the presented conditions are respected. We also anticipate our work to be a starting point for other studies in the wave domain. For example, compact, multiband, beam-steerable microphones...

APs are installed in complex environments and require PoE power supply over a distance of more than 100 m. In some special scenarios, the power supply distance will be much longer. For example, APs in some stadiums require 300 m or even longer power supply distances. The conventional twisted...
Spatio-temporally modulated impedance surfaces can be good candidates for generation of radiating waves with arbitrary eigenstates by breaking momentum and energy conservations. Here, we present a theoretical framework based on the holographic technique
One example of such an operation resides in the use of the transmitter being carried by an underground boring tool. Another example of such an operation resides in moving the transmitter through a pre-existing borehole or path within the ground. Operations that may use such a pre-existing ...
