Our Technology is plasmonics communication

Saltenna can communicate through sea water.

Underwater & Along Surfaces

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

Saltenna can communicate in terrestrial environments.


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

Saltenna's technology has endless capabilities.

Potential Capabilities

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


Saltenna can fully customize communications solutions.

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.

saltenna technology allows you to communicate through seawater with 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
