CPC H01Q 3/46 (2013.01) | 6 Claims |
1. A phase control device comprising:
a phase control lens including at least two metamaterial boards arranged in a first direction and separated from each other, each metamaterial board shifting a phase of electromagnetic wave passing therethrough; and
a control circuit configured to control admittance distribution in a plane perpendicular to the first direction of each metamaterial board, wherein
a principal surface of each metamaterial board is perpendicular to the first direction,
the metamaterial board comprises a two-dimensional array of three-dimensional units that are two-dimensionally arranged in a plane parallel to the principal surface and is configured to shift the phase of electromagnetic wave passing therethrough,
the control circuit controls each three-dimensional unit to adjust a phase delay amount of each three-dimensional unit provided to the electromagnetic wave,
each three-dimensional unit is configured in such a manner that a state of that can be switched to control the phase delay amount of each three-dimensional unit,
the control circuit switches the state of each three-dimensional unit, and
when the state of each three-dimensional unit is changed, the phase delay amount of each three-dimensional unit provided to the electromagnetic wave is changed.
