Pattern-Reconfigurable Water Horn Antenna
IEEE Transactions on Antennas and Propagation, 2021 A novel horn antenna is reported in this communication, which is realized by using water walls instead of traditional metallic walls. Due to its fluidity, water filling different channels can be readily controlled. Therefore, the proposed water horn antenna can operate in two states: H-plane horn state and leaky-wave state, resulting in different ...

Reconfigurable water antennas [PDF]
2014 IEEE Conference on Antenna Measurements & Applications (CAMA), 2014 This paper introduces two types of reconfigurable water antennas. One is a water-grating leaky-wave antenna and the other is a sea-water monopole antenna. The water-grating leaky-wave antenna consists of a parabolic reflecting surface-wave launcher and a periodic water-grating structure, which is designed for wide-angle beam-scanning.

An All‐Optical Driven Bio‐Photovoltaic Interface for Active Control of Live Cells
Advanced Functional Materials, EarlyView.Bio‐photovoltaic Interface (BIO‐PV‐I) for live cell manipulation is presented. BIO‐PV‐I can be activated non‐invasively and remotely to control the spatial motility, adhesion, and morphology of cells adhering to it. BIO‐PV‐I uses a patterned light‐induced electric potential in iron‐doped lithium niobate crystals whose light‐driven and reversible nature,
