Synthetic aperture radar imaging below a random rough surface
Arnold D. Kim, Chrysoula Tsogka
Motivated by applications in unmanned aerial based ground penetrating radar for detecting buried landmines, we consider the problem of imaging small point like scatterers situated…
Synthetic aperture imaging of dispersive targets
Arnold D. Kim, Chrysoula Tsogka
We introduce a dispersive point target model based on scattering by a particle in the far-field. The synthetic aperture imaging problem is then expanded to identify these targets a…
Tunable high-resolution synthetic aperture radar imaging
Arnold D. Kim, Chrysoula Tsogka
We have recently introduced a modification of the multiple signal classification (MUSIC) method for synthetic aperture radar. This method depends on a tunable, user-defined paramet…
High-resolution, quantitative signal subspace imaging for synthetic aperture radar
Arnold D. Kim, Chrysoula Tsogka
We consider synthetic aperture radar imaging of a region containing point-like targets. Measurements are the set of frequency responses to scattering by the targets taken over a co…
Dynamics of Acoustically Bound Particles
Nicholas St. Clair, Dominique Davenport, Arnold D. Kim +1
It is well known that acoustic fields can produce forces on single particles, however they can also induce inter-particle forces due to multiple scattering events. This multi-parti…
Quadrature by Parity Asymptotic eXpansions (QPAX) for scattering by high aspect ratio particles
Camille Carvalho, Arnold D. Kim, Lori Lewis +1
We study scattering by a high aspect ratio particle using boundary integral equation methods. This problem has important applications in nanophotonics problems, including sensing a…
Asymptotic approximations for the close evaluation of double-layer potentials
Camille Carvalho, Shilpa Khatri, Arnold D. Kim
When using the boundary integral equation method to solve a boundary value problem, the evaluation of the solution near the boundary is challenging to compute because the layer pot…
Close evaluation of layer potentials in three dimensions
S. Khatri, A. D. Kim, Ricado Cortez +1
We present a simple and effective method for evaluating double-and single-layer potentials for Laplace's equation in three dimensions close to the boundary. The close evaluation of…
Asymptotic analysis for close evaluation of layer potentials
Camille Carvalho, Shilpa Khatri, Arnold D Kim
We study the evaluation of layer potentials close to the domain boundary. Accurate evaluation of layer potentials near boundaries is needed in many applications, including fluid-st…
