Abstract
Highly directional scatterers are designed using coreshell microspheres. Their structural parameters are optimized analytically by genetic algorithm to optimize directional scattering, and the results are verified by finite difference time domain calculations. Using such optimized directional scatterers, the front-to-back ratio and directivity of a dipoleis enhanced to 9 and 4.4 respectively.
