What are electromagnetic metamaterials?
Electromagnetic metamaterials are designed to have unique structural and chemical properties that are not natural for materials. Nanoparticle surfaces that can affect the reaction of metamatrial to common light, as well as other types of radiation, such as microwave radiation, are formed, the fact that structural features are less than the actual wavelength of radiation. The properties of such electromagnetic metamaterials are often created to display that include unique dielectric effects, as well as a negative refractive index with silver metamators that could be used to create superlells that could solve, have several nanometers, or are used to look at internal non -magnetic objects. Research of such materials in 2011 was in microwave engineering for advanced antennas and other magnetically related systems. These structured materials are capable of developing magnetism in the presence of microwave or terrahertz-infrared afterLess that exist directly between the microwave and the visible range of lights of the electromagnetic (EM) spectrum. Otherwise, such materials would be non -magnetic and the stimulation of this feature in them is referred to as the creation of the behavior of the left hand (LH) in physics. Creating such behavior in non -magnetic devices would be helpful in the production of advanced filters and electronics to move beams or phase shifts.
The use of metamators would further miniaturized electronic components and would also create circuits and antennas selectively sensitive or impermeable for different strips of EM. An example of one application for a finer level of inspection over electromagnetic waves would be in global positioning technology (GPS) that could transmit or block a more accurate positioning signal than is currently possible in military targeting and interference. This increased ability is made possibleElectromagnetic metamaterials are an artificially structured material form that interacts and controls the surrounding electromagnetic waves, so that the materials are transmitters and receivers.
types of metamators that show these properties have structural features created on the scale of angstrom or in the size of about one tenth of nanometer. This requires the common efforts of several areas of science on the construction of such materials, including physics, chemistry and engineering in nanotechnology and material science. Gold, silver and copper metals, as well as plasma and photonic crystals are the materials that are used in the construction of such electromagnetic metamatures, and as science progresses, it finds the use of materials in the field of optics. This is theorized that the form of an electromagnetic field of invisibility could eventually be created by metamators where visible light could be bent around them to cover their presence.
