description The present specification provides a method and apparatus, the method being for transmitting a beam, performed by the apparatus, in an optical wireless communication system, and comprising: generating a pulse laser signal; making the pulse laser signal to be incident on a metasurface, wherein the beam is generated on the basis that the pulse laser signal is incident on the metasurface; and transmitting the beam to a reception apparatus, wherein the metasurface is determined on the basis of ω_0, d, Δω, and N, wherein ω_0 is a value of a center frequency, d is a value of a virtual antenna interval, Δω is a value of a frequency comb interval, and N is a value related to the number of frequency combs present within a gain bandwidth based on the center frequency.
