Our Technology is plasmonics communication

Underwater & Along Surfaces
Plasmonics provide physically secure, undetectable, RADAR, broadband video, voice, and data communications from submerged machine to machine. Demonstrations available.

Terrestrial
Communications and imaging through fortified underground bunkers and tunnels, using Plasmonics.

Potential Capabilities
From transmitting through metal walls to medical imaging to oil and gas applications, over-the-horizon (OTH) RADAR, terrestrial RADAR, and more.

Plasmonic Based Designs
You give us the desired objectives (variables: material, power, bandwidth, distance, depth, etc.) and what you’d like to achieve, and we will engineer a solution of optimized Plasmonics.

Underwater and Along Surfaces – beyond the horizon
Design and build smarter using surfaces
Our technology utilized Plasmonics, which uses conductivity mismatches (e.g., air to sea or sea to seafloor interfaces, metal to air, subterranean stratified ground layers, etc.) to transmit high bandwidth data or dielectric imaging, far exceeding traditional skin-depth estimates.
Safe for marine life
Traditional acoustic communication can be incredibly disruptive for marine wildlife, particularly mammals that use acoustics to communicate. Plasmonics are tightly coupled to the ocean’s surface, which doesn’t disturb marine life.
Lower size, weight, and power, yet more effective
In comparison to conventional RF, acoustic, or laser configurations, Saltenna’s antenna-like devices provide at least 10-100x improvement, while not sharing their challenges in related environments.
Terrestrial (including Penetrating)
Imaging and communication through or within fortified tunnels or bunkers
Our technology can transmit high bandwidth RF communications through fortified bunkers, including imaging, video, and RADAR.
Dielectric characterization
Characterize dielectric materials while imaging: biological, metal, plastic, etc.
"FutureG" wi-fi & sensing-through-the-walls (STTW)
Communications and imaging can be provided in complex building environments (metals, clay, concrete, and other buildable materials) using Plasmonic surface electromagnetic waves , even through secure workspaces.
