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…

Interplay of linear and modified nonlinear impurities in the formation of stationary localized states
Bikash C. Gupta, Sang Bub Lee
Formation of stationary localized states in one-dimensional chain due to a linear impurity and a modified nonlinear impurity is studied. Furthermore, a one-dimensional chain with l…

Interplay of linear and nonlinear impurities in the formation of stationary localized states
Bikash C. Gupta, Sang Bub Lee
Formation of stationary localized states in one-dimensional chain as well as in a Cayley tree due to a linear impurity and a nonlinear impurity is studied. Furthermore, a one-dimen…
