Yi J, Radosevich A, Rogers J, Norris S, Capoglu I, Taflove A, et al.
Opt Express . 2013 Apr; 21(7):9043-59. PMID: 23571994
Exploration of nanoscale tissue structures is crucial in understanding biological processes. Although novel optical microscopy methods have been developed to probe cellular features beyond the diffraction limit, nanometer-scale quantification remains...

Capoglu I, Taflove A, Backman V
Opt Express . 2013 Feb; 21(1):87-101. PMID: 23388899
We demonstrate how a tightly-focused coherent TEMmn laser beam can be computed in the finite-difference time-domain (FDTD) method. The electromagnetic field around the focus is decomposed into a plane-wave spectrum,...

J Biomed Opt . 2012 Nov; 17(11):115001. PMID: 23123973
ABSTRACT. We present an open source electric field tracking Monte Carlo program to model backscattering in biological media containing birefringence, with computation of the coherent backscattering phenomenon as an example....

Rogers J, Stoyneva V, Turzhitsky V, Mutyal N, Pradhan P, Capoglu I, et al.
Opt Express . 2011 Jul; 19(13):11922-31. PMID: 21716426
Enhanced backscattering (EBS), also known as weak localization of light, is derived using the Huygens-Fresnel principle and backscattering is generally shown to be the sum of an incoherent baseline and...

Capoglu I, White C, Rogers J, Subramanian H, Taflove A, Backman V
Opt Lett . 2011 May; 36(9):1596-8. PMID: 21540939
Rigorous numerical modeling of optical systems has attracted interest in diverse research areas ranging from biophotonics to photolithography. We report the full-vector electromagnetic numerical simulation of a broadband optical imaging...

Capoglu I, Rogers J, Taflove A, Backman V
Opt Lett . 2009 Sep; 34(17):2679-81. PMID: 19724530
A rigorous error analysis is presented for the scattering coefficient of biological random continuous media in the Born (or single-scattering) approximation. The analysis is done in two dimensions (2-D) for...

Capoglu I, Taflove A, Backman V
Opt Express . 2009 Jul; 16(23):19208-20. PMID: 19582013
A straightforward procedure is described for accurately creating an incident focused light pulse in the 3-D finite-difference time-domain (FDTD) electromagnetic simulation of the image space of an aplanatic converging lens....

Rogers J, Capoglu I, Backman V
Opt Lett . 2009 Jun; 34(12):1891-3. PMID: 19529738
A three-parameter model based on the Whittle-Matérn correlation family is used to describe continuous random refractive-index fluctuations. The differential scattering cross section is derived from the index correlation function using...

Subramanian H, Pradhan P, Liu Y, Capoglu I, Rogers J, Roy H, et al.
Opt Lett . 2009 Apr; 34(4):518-20. PMID: 19373360
Existing optical imaging techniques offer us powerful tools to directly visualize the cellular structure at the microscale; however, their capability of nanoscale sensitivity is restricted by the diffraction-limited resolution. We...

Proc Natl Acad Sci U S A . 2008 Dec; 105(51):20118-23. PMID: 19073935
Recently, there has been a major thrust to understand biological processes at the nanoscale. Optical microscopy has been exceedingly useful in imaging cell microarchitecture. Characterization of cell organization at the...
