Abstract
Electromagnetic wave focusing devices and optical apparatuses including the same are provided. An electromagnetic wave focusing device may include a plurality of material members located at different distances from a reference point. The intervals and/or widths of the material members may vary with distance from the reference point. For example, the intervals and/or widths of the material members may increase or decrease with distance from the reference point. The intervals and/or widths of the material members may be controlled to satisfy a spatial coherence condition with the electromagnetic wave.
