A metamaterial (from the Greek word μετά meta, meaning "beyond" or "after", and the Latin word materia, meaning "matter" or "material") is a type of material engineered to have a property, typically rarely observed in naturally occurring materials, that is derived not from the properties of the base materials but from their newly designed ...
The “mechanical metamaterial tree of knowledge” [13] implies that chiral, lattice and negative metamaterials (e.g., negative bulk modulus or negative elastic modulus) are ripe followed by origami and cellular metamaterials. Recent research trends have been entering a space beyond merely exploring unprecedented mechanical properties.
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]
Metamaterials are artificial materials engineered to provide properties which may not be readily available in nature. These materials employ the inclusion of small inhomogeneities to enact effective macroscopic behavior.
A nonlinear metamaterial is an artificially constructed material that can exhibit properties not yet found in nature. Its response to electromagnetic radiation can be characterized by its permittivity and material permeability .
An acoustic metamaterial, sonic crystal, or phononic crystal is a material designed to manipulate sound waves or phonons in gases, liquids, and solids (crystal lattices).By carefully controlling properties such as the bulk modulus β, density ρ, and chirality, these materials can be tailored to interact with sound in specific ways, such as transmitting, trapping, or amplifying waves at ...
She also pointed out that the definition of “a drink” may vary. “Many individuals don’t pour an actual serving size (5 ounces for wine, 12 ounces for beer, ...
Metamaterial antennas are a class of antennas which use metamaterials to increase performance of miniaturized (electrically small) antenna systems. [1] Their purpose, as with any electromagnetic antenna, is to launch energy into free space.
