Antenna designs incorporating metamaterials can improve the radiated power of an antenna. The newest metamaterial antennas radiate as much as 95 percent of an input radio signal. Standard antennas need to be at least half the size of the signal wavelength to operate efficiently. At 300 MHz, for instance, an antenna would need to be half a meter ...
Metamaterial antennas are a class of antennas that use metamaterials to improve performance. [15] [21] [85] [86] Demonstrations showed that metamaterials could enhance an antenna's radiated power. [15] [87] Materials that can attain negative permeability allow for properties such as small antenna size, high directivity and tunable frequency ...
Kymeta was founded in August 2012 after spinning out from Intellectual Ventures and manufactures software-enabled, meta-materials based electronic beamforming antennas and terminals for satellite communications. [2] Founder Nathan Kundtz served as the CEO until 2018. [3]
There are two of these, standing vertical, side by side, instead of lying flat, in the unit cell. In 2005 these were considered to be a new type of metamaterial. One set of cited dimensions are annular parameters of R=1.4 mm and r=1 mm, and the straight edge is 3.33 mm. [24] Another new metamaterial in 2005 was a coupled S-shaped structure ...
A tunable metamaterial is a metamaterial with a variable response to an incident electromagnetic wave. This includes remotely controlling how an incident electromagnetic wave (EM wave) interacts with a metamaterial.
A photonic metamaterial (PM), also known as an optical metamaterial, is a type of electromagnetic metamaterial, that interacts with light, covering terahertz , infrared (IR) or visible wavelengths. [1] The materials employ a periodic, cellular structure.
A terahertz metamaterial is a class of composite metamaterials designed to interact at terahertz (THz) frequencies. The terahertz frequency range used in materials research is usually defined as 0.1 to 10 THz .
