| Popis: |
Experimental investigations of the focusing behavior of rods having acoustically graded‐index profile across the rod diameter are presented for the first time. The ray acoustics approach is used for the theoretical interpretation. Acoustic velocity profiles have been measured using a 225 MHz line focus beam scanning acoustic microscope. The focusing behavior is visualized with a Schlieren system. |
