  Abstract

We designed that a two-dimensional acoustic Luneberg lens for ultrasound with a diameter of 90mm and 15 layers. The acoustic Luneberg lens is composed of 701 columns with square cross section made of SUS304 whose sizes were different from each columns placed at the center of the square grid with one side of 3mm in length. Using computer simulation program(COMSOL), we confirmed that the plane wave was focused after being passed by the acoustic Luneberg lens and got the SPL gain in air and water condition. The focal point was stable at 20~35kHz in air and 100~180kHz in water. The maximum SPL gain of the acoustic Luneburg lens were 15dB@32kHz in air and 12dB@175kHz in water.
