This paper is concerned with the design of reconfigurable antennas based on pure water.
Being a transparent, flexible, and readily available liquid, pure water can form a cylindrical …

A novel single‐fed dual‐band circular‐polarization (CP) reconfigurable liquid dielectric
resonator antenna (LDRA) using 3D printing technology is proposed in this article. With the …

We investigate the directional control of narrow-band perfect thermal emission using a
nanoscale Yagi–Uda antenna. Although Yagi–Uda antennas were demonstrated to achieve …

A generic field analysis technique for a liquid antenna along with a novel high‐gain structure
of water antenna is presented in this article. The antenna design has liquid material as a …

This letter proposed a water antenna with a novel shape of a hemispherical helix made of
pure water. A plastic water pipe is bent into a hemispherical helix and filled with water to …

In this study, a pure water antenna with a tunable radiation pattern is proposed, which
combines the idea of the Yagi antenna and the reflector antenna to realize a steerable …
