Experimental evidence of quadrupolar whispering-gallery modes in phononic crystal based waveguides

Understanding the performance of resonators introduced in elastic and/or acoustic circuits is important for conceiving complex and efficient guiding structures. In this work, we reported upon the experimental characterization of hollow pillars in different waveguides with 90° corners by measuring th...
