Analysis of microwave propagation in arrays of dielectric cylinders
Bikash C. Gupta, Zhen Ye
We rigorously compute the propagation and scattering of microwaves by regular and defected arrays of dielectric cylinders in a uniform medium. Comparison with the previous experime…
Focusing of electromagnetic waves by periodic arrays of dielectric cylinders
Bikash C. Gupta, Zhen Ye
By numerical simulations, we show that properly arranged two dimensional periodic arrays, formed by dielectric cylinders embedded in parallel in a uniform medium, can indeed act as…
Theoretical analysis of the focusing of acoustic waves by two-dimensional sonic crystals
Bikash C. Gupta, Zhen Ye
Motivated by a recent experiment on acoustic lenses, we perform numerical calculations based on a multiple scattering technique to investigate the focusing of acoustic waves with s…
Are waves all localized in two dimensional random media?
Zhen Ye
It has been the dominant view for over two decades that all waves are localized in two dimensions for any given amount of disorder. Here, I would like to raise questions about this…
Localization of electromagnetic waves in two-dimensional random dielectric systems
Bikash C. Gupta, Yu-Yu Chen, Zhen Ye
We rigorously calculate the propagation and scattering of electromagnetic waves by rectangular and random arrays of dielectric cylinders in a uniform medium. For regular arrays, th…
Localization of classical waves in two dimensional random media: A comparison between the analytic theory and exact numerical simulation
Bikash C. Gupta, Zhen Ye
The localization length for classical waves in two dimensional random media is calculated exactly, and is compared with the theoretical prediction from the previous analytic theory…
