Embodiment Construction

[0071] Referring now in detail to the embodiments, examples of which are illustrated in the drawings, wherein like reference numerals refer to like elements throughout. In this regard, the presented embodiments may have different forms and should not be construed as being limited to the descriptions set forth herein. Accordingly, the embodiments are merely described below, by referring to the figures, to explain various aspects. As used herein, the term "and / or" includes any and all combinations of one or more of the associated listed items. Expressions such as "at least one of," when preceding a list of elements modify the entire list of elements and do not modify the individual elements of the list. For example, the expression "at least one of a, b, and c" should be read to include: only a, only b, only c, both a and b, both a and c, both b and c, a, b and all of c, or any variation of the preceding examples.

[0072] Hereinafter, embodiments will be described in detail w...

Abstract

A metasurface optical device includes: a plurality of phase modulation regions configured to modulate a phase of incident light, each of the plurality of phase modulation regions including a plurality of nanostructures, a shape and arrangement of the plurality of nanostructures being determined according to a respective rule set for each of the plurality of phase modulation regions; and a compensation region between a k-th phase modulation region and a (k + 1)-th phase modulation region adjacent to each other among the plurality of phase modulation regions and including a compensation structure, and a compensation structure for buffering an effective refractive index change occurring in a boundary region between a k-th phase modulation region and a (k + 1)-th phase modulation region according to respective rules of the k-th phase modulation region and the (k + 1)-th phase modulation region, where N is a number of the plurality of phase modulation regions, k and N are natural numbers, and k is equal to or greater than 1 and less than N.

Description

[0001] Cross References to Related Applications [0002] This application claims priority to Korean Patent Application No. 10-2020-0120029 filed with the Korean Intellectual Property Office on September 17, 2020, the disclosure of which is hereby incorporated by reference in its entirety. technical field [0003] Apparatuses and methods consistent with example embodiments relate to a meta-optics device and an electronic device including the meta-optics device. Background technique [0004] Planar diffractive devices including metastructures can exhibit various optical effects that may not be possible with conventional refractive devices. Therefore, such planar diffractive devices can be used to realize thin optical systems, and thus, interest in using thin optical systems in many fields has increased. [0005] Metastructures include nanostructures in which values ​​smaller than the wavelength of incident light are applied to shape, period, and the like. The nanostructure i...
