Abstract
AbstractThe rise of water‐based electromagnetic devices opens up new possibilities for controlling electromagnetic performance due to the liquid state of crucial parts of the device. This letter proposes the siphon mechanism as a novel way to achieve reconfigurability in these types of electromagnetic devices. To demonstrate this, a simple polarization‐reconfigurable device based on a siphon is introduced. The device is designed to scatter horizontal and vertical polarizations differently depending on the amount of water added to it. The siphon mechanism offers a sharp transition between two states after water is added above a threshold. The device is simulated, manufactured using 3D printing, and measured in different states filled with both distilled and tap water. The results demonstrate that polarization reconfigurability is achieved with the different states scattering the two polarizations as expected. Siphons similar to this could be used to offer new types of control in other electromagnetic devices based on liquids.
