New space missions require new types of communication. Plasmonic technology can make it possible to make more effective, and more secure data transportation protocols. The other tools are spinning micro- and radio waves. Or the system can use plasmoid channels and spintronics to create high-accurate thin-band data transmission that is protected from outside effects.
High-speed data transportation requires systems that can protect data against outside, purpose, and non-purpose effects. In some models, the system can transport data using highly accurate maser technology and coherent radio waves that travel in radio wave vortexes or channels. The data can travel in spinning radio- or microwaves.
Or in data transmission, the system can use (as an example) radiowaves to transmit 1 and microwaves to transmit 0. The laser rays that travel in another laser ray are also promising things. The outside channel denies outsides to see the data, that travels in the data transmission.
"In physics, a plasmon is a quantum of plasma oscillation. Just as light (an optical oscillation) consists of photons, the plasma oscillation consists of plasmons. The plasmon can be considered as a quasiparticle since it arises from the quantization of plasma oscillations, just like phonons are quantizations of mechanical vibrations. Thus, plasmons are collective (a discrete number) oscillations of the free electron gas density. For example, at optical frequencies, plasmons can couple with a photon to create another quasiparticle called a plasmon polariton." (Wikipedia, Plasmon)

The system transforms plasma oscillation into the data that the laser wave transports. The idea is that the laser ray travels over oscillating plasma. That oscillation can make a similar image that is made in light-based computing (Above). In plasmonic systems, the plasma replaces that image.
"Think of it like layers in an image editing application such as Adobe Photoshop: You have an input layer — source image — which can have layers placed on top, that obscure, manipulate or transmit something from the layer beneath. The output — top layer — is essentially processed by the combination of these layers. In this case, these layers will have light passed through them casting an image (hence the “casting” in diffraction casting) on a sensor, which will then become digital data for storage or presentation to the user."

"Scientists have achieved data rates as high as 424Gbit/s across a 53-km (33-mile) turbulent free-space optical link using plasmonic modulators—devices that use special light waves called surface plasmon polaritons to control and modify optical signals. This new research establishes the foundation for high-speed optical communication links that transmit data through open air or space."

"In physics, polaritons are quasiparticles resulting from the strong coupling of electromagnetic waves with an electric or magnetic dipole-carrying excitation." (Wikipedia, polariton)
As you see from the diagram above the plasmonic communication system looks like axons. So, plasmonic communication makes it possible to create new tools for hardware-based artificial intelligence. The plasmonic systems can emulate human axons. The ion and anion particles can act as neurotransmitters. And that thing makes the plasmonic communication more effective than we ever thought.
