Abstract: Provided is a tunable electro-optic filter including a reflective structure including a first reflective layer including a first pattern layer having a first meta-surface structure disposed on a first side of the liquid crystal layer and a second reflective layer including a second pattern layer having a second meta-surface structure disposed on a second side of the liquid crystal layer. Each of the first meta-surface structure and the second meta-surface structure includes multiple dielectric materials which are alternately stacked, and a thickness of each dielectric material gradually increases. Alternately, the tunable electro-optic filter may include a pattern layer having a meta-surface structure disposed on at least a side of the liquid crystal layer.
