Underwater optical-acoustic hybrid networking can complement the advantages of both
underwater wireless optical and acoustic communications, which holds great development …

Underwater sensor networks are anticipated to facilitate numerous commercial and military
applications. Moreover, precise self-localization in practical underwater scenario is a crucial …

Conventional wireless communication faces limitations in underwater environments due to
the high electromagnetic wave attenuation. Ultrasound provides an alternative, enabling …

The optoacoustic effect is triggered by directing an optical signal in the air (using laser) to
the surface of water, leading to the generation of a corresponding acoustic signal inside the …

Nonlinear optoacoustics enable effective communication across the air-water interface.
However, the requirement of a high-power laser and the vapor cloud buildup can limit the …

INTRODUCTION: Ever since the initial discovery of superconductivity, the fundamental
concept and the complex relationship between critical temperature and superconductive …

To realize the information transmission across the water–air interface, the radar has been
used to detect the tiny surface perturbations caused by the underwater low-frequency sound …

Optoacoustic communication enables an airborne unit to directly reach nodes deep
underwater. To achieve high data rates in optoacoustic communications, implementing a …

In this paper, we demonstrated a high-energy (285 mJ) mid-infrared flashlamp-pumped
electro-optically Q-switched Er: YAG master oscillator power amplifier (MOPA) system and …

Wireless communication from air-to-underwater is quite challenging because of the lack of
proper physical signal that propagates well in both air and water medium. Photoacoustic …
