Manipulating waves with engineered metamaterials
- Metamaterials are engineered materials with unique properties not found in nature, often used to manipulate light, sound, and electromagnetic properties.
- These materials are distinct from naturally occurring substances like metals, alloys, semiconductors, ceramics, and plastics, which are manufactured from scratch.
- Metamaterials primarily focus on manipulating waves of light and sound, as well as electromagnetic properties on a macro scale.
- The theoretical applications of advanced materials include Computronium, Neutronium, strange matter, and smart matter, each with unique properties and potential uses.
- The main characteristic of metamaterials is their ability to manipulate waves of light and sound, as well as electromagnetic properties on a macroscale.
- Metamaterials require both negative permeability and negative permittivity to achieve a negative refractive index, which allows for unique properties like negative refraction.
- To create metamaterials, geometric patterns are constructed using materials with negative permeability and negative permittivity, arranged in repeating patterns called 'cells'.
- Metamaterials are designed to manipulate light, electromagnetic radiation, or sound waves, with individual elements smaller than the wavelength of the waves they affect.
- Radio-based metamaterials are well understood and created by combining materials with negative permeability and negative permittivity to achieve a negative refractive index.
- Metamaterials have practical applications such as creating perfect lenses for focusing radiation, tuning specific frequencies for better signal quality, and compensating for the doppler effect in spacecraft communication.

"Advanced Technology Aids Successful Enemy Scouting"
- Romulus' unit rests after a hard day on the battlefield, needing heavy batteries to power their electronic equipment.
- Romulus uses solar panels to recharge the equipment and sets up a satellite uplink for further orders, struggling to point it in the right direction.
- The encrypted communications gear drains power quickly due to enemy detection and decoding, making Romulus worry about battery life and slow transmissions.
- Despite solar panel operation, battery charge remains low, causing concern about mission completion.
- Romulus receives orders to scout an enemy encampment, capturing images with limited zoom capability due to bulky lenses.
- Romulus' squad is spotted, leading to a hasty retreat under enemy fire, delaying footage transmission to superiors.
- Remus has advanced metamaterial equipment, including camo and chameleon suits, lightweight batteries, and efficient solar panels.
- Remus easily captures images of the enemy camp from a distance, remaining undetected due to advanced technology.
- Remus' squad successfully scouts the enemy camp and makes a clean getaway, contrasting Romulus' experience.
