- Swiss roll (metamaterial)
Swiss roll is a type of optical
metamaterialthat has negative refractive index. It is named for its resemblance to the confectionery swiss roll: it consists of concentric cylinders of insulated metal.
Swiss roll finds applications in
magnetic resonance imaging; typically, an array of Swiss rolls is used as a flux ducting mechanism.
