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

Potential Capabilities

From transmitting through metal walls to medical imaging to oil & 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 & Along Surfaces – beyond the horizon

Design & build smarter using surfaces

Our technology uses Plasmonics that use conductivity mismatches (e.g., air-sea or sea-seafloor interfaces, metal-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 via marine-life Safe RF.

Lower size, weight, 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 (incl. 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 & imaging can be provided in complex building environments (metals, clay, concrete, other buildable materials) using our Plasmonic surface electromagnetic waves (Plasmonics), even through secure workspaces.

Potential Capabilities

Improving 5G - expanded coverage and through conductive enclosures

Continuous communications through hypersonic plasma

Medical imaging

Plasmonics Based designs

Saltenna can implement solutions to your communications problems according to your performance, size, weight, or power needs.
