We utilize Plasmonics to transmit through seawater, ground, metal walls, and more.

We specialize in Advanced Electromagnetics and Metamaterials to produce performance enhancing Plasmonics antenna-like devices and technologies.

What we do

Underwater & Along the Surfaces

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


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.

Mission & Vision

Enabling novel high bandwidth wireless communications & imaging through seawater and conductive enclosures.

Our Technology is plasmonics communication

We pride ourselves by making previously impossible transmissions, communications, and imaging possible. 99.999% operationally available and reliable. We build novel, game changing antenna-like devices and systems to provide superior performance through the harshest environments.

Plasmonics - surfaces, a new way to communicate

We use Plasmonics to transmit high bandwidth data. Due to a different physical mechanism of transmission, we can communicate in environments that traditional RF, acoustics, and lasers traditionally underperform or fail.

Transmit through or along the surface of seawater

We have developed several patented antenna-like devices and systems which significantly increase capacity for high-frequency RF signal transmissions through or along the surface of seawater, while providing a considerable performance advantage over other currently used undersea communication techniques. Based on initial testing, our technology provides 10-100 times improvement in size, weight, and power applications maintaining superior performance over our competitors

Breaching or enhancing physical environments (even secure)

Sense-through-the walls, communications through or within secure workspaces, & penetrating RADAR/Imaging with dielectric characterization. Add secure resiliency to your communications system. Or, just improve the wi-fi in your building, home, or warehouse (“FutureG”).


The Saltenna Advantage; where or when you cannot sense, scan, or communicate… please contact Saltenna.

Make previously impossible transmissions, communications, and imaging possible. Or, enhance your current platform’s performance by 10-100x, additionally with SWaP-C benefit. 99.999% operationally available and reliable. We build novel, game changing antenna-like devices and systems to provide superior performance in the harshest environments.


UUV Compact High-Freq/Broadband Communications in Sea Water

Novel patented antenna-like devices use Plasmonics which “transmit” differently, along surfaces vice “free-space.”

RADAR Scanning via High-Freq/Broadband in Sea Water

This new capability will provide undetected RADAR imaging underwater.

Superior Submarine Technology

Saltenna equipped submarines can out-perform conventional submarine communications in a variety of ways.

5G/Wi-Fi Transmissions Through Conductive Enclosures & Secure Workspaces

Our patented antennas are optimized for excitation of partially longitudinal waves (such as Plasmons, etc.) in combination with patent-pending novel impedance matching techniques; Plasmons do “impossible” things!

Sense Through the Walls (STTW)

See how Saltenna’s technology can penetrate walls and bunkers of secure environments.

Ground Penetrating RADAR (GPR)

Imaging through fortified underground bunkers and tunnels, characterizing dielectric materials: bio, metal, plastic, and more within.
