Abstract
An object is to actively control a phase of electromagnetic wave with high efficiency. A phase control device includes a phase control lens and a control circuit. The phase control lens includes metamaterial boards arranged in a first direction and separated from each other. Each metamaterial board shifts a phase of electromagnetic wave passing therethrough. The control circuit controls admittance distribution in a plane perpendicular to the first direction of each metamaterial board.
