## Metamaterial cloaking

Metamaterial cloaking is the usage of metamaterials in an invisibility cloak. This is accomplished by manipulating the paths traversed by light through a novel optical material. Metamaterials direct and control the propagation and transmission of specified parts of the light spectrum and demonstrate the potential to render an object seemingly invisible. Metamaterial cloaking, based on transformation optics, describes the process of shielding something from view by controlling electromagnetic radiation. Objects in the defined location are still present, but incident waves are guided around them without being affected by the object itself. Basically, bending or distorting light to electromagnetically conceal an object.

The purpose of a cloaking device is to hide something, so that a defined region of space is invisibly isolated from passing electromagnetic fields (or sound waves), as with Metamaterial cloaking.

Cloaking objects, or making them appear invisible with metamaterials, is roughly analogous to a magician's sleight of hand, or his tricks with mirrors. The object or subject doesn't really disappear; the vanishing is an illusion. With the same goal, researchers employ metamaterials to create directed blind spots by deflecting certain parts of the light spectrum (electromagnetic spectrum).

## Bio-engineered plant-based camouflage

Genetically modified, or transgenic, plants are any plant that contains any gene or genes that have been artificially inserted into the plant instead of being acquired by the plant through pollination. One could bioengineer a sub product of a cactus (pretty good at absorbing EMF radiation) with a fungus or some other sort of creeping plant that will allow for great coverage of ships with minimal intrusion due to the large surface area without increasing their height. Genes could also be introduced in these plants to control them. A control panel could be engineered to send signals to these plants through water or shocks.

“While NASA does study plants and considers radiation (without Earth’s protective atmosphere, space has much higher levels of harmful radiation than on the Earth’s surface), their studies are about how well plants survive in such conditions, not about their capabilities to block or absorb radiation.

If you take the time to read this study people are talking about, you’ll see that the Space Agency was trying to figure out what plants would be best in a greenhouse as part of the first human outpost on Mars. They found five suitable plants that absorb ionizing radiation, and cactus is the one we hear more about. But they looked more specifically at plants that could survive extreme temperature swings and tons of sunlight with absolutely no protective ozone. “

## Stationary or slow-moving ships camouflage

Going back to Metamaterial cloaking, using an electromagnetic field, a sort of dust particle cloud electromagnetically controlled (Maybe not) to flow around the ship providing the same cloaking abilities as the first one but on a larger scale sacrificing movement speed. This is much harder to achieve because of the way metamaterials work. Since they’re used to “Dodge the electromagnetic field”, using one to keep them close to the ship would be insane. My 3 ways of making this work is:

1. Magnetic fields
2. Nano tech
3. Gravity fields

If the technology is available, #3 Is probably the best bet to make this work without giving away the position and keeping it realistic.
