Abstract
A liquid crystal is configured as a photonic crystal by an establishment of a network of biased liquid crystal regions within the liquid crystal. The liquid crystal is situated between a dielectric plane including an electrode plate and a glass plate, and a dielectric plane including a glass plate and a plurality of electrode pixels. The network is established by a selective application of one or more electric potentials between an electrode plate and one or more of the electrode pixels.
Claims12
An electromagnetic waves interaction device, comprising:
- a liquid crystal;
- an electrode plate;
- and
- a plurality of electrode pixels,
- wherein said electrode plate and said plurality of electrode pixels are operable to configure the liquid crystal as a photonic crystal in response to a selective application of one or more electric potentials between said electrode plate and one of more of the electrode pixels.
An electromagnetic waves interaction device, comprising:
- a liquid crystal;
- an electrode plate;
- and
- a plurality of electrode pixels,
- wherein an electrical interaction between said electrode plate and one or more said plurality of electrode pixels operates to establish a network of biased liquid crystal regions within said liquid crystal.
An electromagnetic waves interaction device, comprising:
- a liquid crystal;
- an electrode plate;
- and
- a plurality of electrode pixels,
- wherein said electrode plate and a first electrode pixel are operable to establish a first biased liquid crystal region within said liquid crystal in response to an application of a first electric potential between said electrode plate and said first electrode pixel.
