Abstract

In the microwave band, the radiated wave from the pyramidal horn antenna is calculated in the diffracted field by the Fresnel approximation. In addition, the Fresnel approximation has been introduced into the diffracted field with half infinite diffraction plane. This phenomenon is examined compared with the experiment value based on a hologram interpretation. In this report, the electromagnetic diffracted field with the pyramid horn antenna is calculated as the first stage under the Fresnel approximation. As a result, the hologram was made by interfering with the reference wave whose obtained diffracted field and angle of incidence are 60° on the computer. It can be interpreted that this is one computer generated hologram. Moreover, the image that this hologram pattern is reconstructed in optics with the He-Ne laser was obtained.
