Acoustic multipole sources from the Boltzmann equation
(Chapter, 2013)By adding a particle source term in the Boltzmann equation of kinetic theory, it is possible to represent particles appearing and disappearing throughout the fluid with a specified distribution of particle velocities. By ... -
Finite-size limitations on quality factor of guided resonance modes in 2D photonic crystals
(Journal article; Peer reviewed, 2013)High-Q guided resonance modes in two-dimensional photonic crystals, enable high field intensity in small volumes that can be exploited to realize high performance sensors. We show through simulations and experiments how ... -
Simulations and realizations of active right-handed metamaterials with negative refractive index
(Journal article; Peer reviewed, 2007)The theory of determining the sign of the refractive index in active materials is discussed. Animations of numerical simulations are presented, supporting the claim that negative refractive index may occur in right-handed ...
