Acoustic Lens Design
Andreas Hakansson, Jose Sanchiz-Dehesa, Lorenzo Sanchis
A survey of acoustic devices for focusing airborne sound is presented. We introduce a new approach to design high quality acoustic lenses based on arrays of cylindrical rigid scatt…
Comment on "Theory of tailoring sonic devices: Diffraction dominates over refraction"
A. Hakansson, J. Sanchez-Dehesa, F. Cervera +3
Recently N. Garcia et al. (Phys. Rev. E 67, 046606 (2003)) theoretically studied several acoustic devices with dimensions on de order of several wavelenghts. The authors discussed…
Integrated Optical Devices Design by Genetic Algorithm
L. Sanchis, A. Hakansson, D. Lopez-Zenon +2
In this work we use multiple scattering in conjunction with a genetic algorithm to reliably determine the optimized photonic-crystal-based structure able to perform a specific opti…
