Spiral of archimedes
WebA spiral is plane curve that, in general, unwinds around a point while moving ever farther from the point. While there are many kinds of spirals, two most important are the Archimedean spiral and the equiangular spiral. The Archimedean spiral is described in polar coordinates by. It was discovered by Archimedes in about 225 BC in a work On Spirals. The Archimedean spiral (also known as the arithmetic spiral) is a spiral named after the 3rd-century BC Greek mathematician Archimedes. It is the locus corresponding to the locations over time of a point moving away from a fixed point with a constant speed along a line that rotates with constant angular velocity. … See more The Archimedean spiral has the property that any ray from the origin intersects successive turnings of the spiral in points with a constant separation distance (equal to 2πb if θ is measured in radians), hence the name "arithmetic … See more One method of squaring the circle, due to Archimedes, makes use of an Archimedean spiral.

Other spirals falling into this group include the hyperbolic spiral (c = −1), Fermat's spiral (c = 2), and the lituus (c = −2).

WebWe have demonstrated both numerically and experimentally a 2D plasmonic metamaterial the unit cell of which comprised an Archimedean spiral with a C-shaped resonator. Such metasurface enables the excitation of spoof localized plasmon resonances (LPRs) in the terahertz frequency range, similar in properties to the familiar LPRs in the visible range.
