Local reconstruction of coefficients in quantitative photo-acoustic tomography
Gang Bao, Mirza Karamehmedovic, Faouzi Triki
We study the problem of reconstructing the scattering and absorption coefficients in the radiative transport equation using internal data in quantitative photo-acoustic tomography…
Programmable photonic nanojets via phase-only time-reversal: a numerical study
Tobias Abilock Mikkelsen, Cristian Placinta, Jesper Glückstad +1
We present a phase-only time-reversal framework for steering photonic nanojets without mechanical motion or amplitude modulation. Time-reversed radiation by a synthetic source plac…
Photonic nanojets as emergent free-space power flux funnels
Mirza Karamehmedović, Cristian Placinta, Tobias Abilock Mikkelsen +1
A reduced local field model derived from full-wave electromagnetic simulations shows that photonic nanojet formation corresponds to an emergent mesoscopic funnel of propagating pow…
Interpolating between Tikhonov regularization and spectral cutoff
Martin Sæbye Carøe, Mirza Karamehmedović, Pierre Maréchal
Regularizing a linear ill-posed operator equation can be achieved by manipulating the spectrum of the operator's pseudo-inverse. Tikhonov regularization and spectral cutoff are wel…
Multi-resolution deconvolution
Mirza Karamehmedović, Pierre Maréchal, Martin Sæbye Carøe +1
We extend the classical deconvolution framework in Rn to the case with a pseudodifferential-like solution operator with a symbol depending on both the base and cotangent variable.…
Rethinking photonic nanojets: a new definition and design paradigm
Mirza Karamehmedović, Kristoffer Linder-Steinlein, Jesper Glückstad
We propose a rigorous, physically interpretable, and quantifiable definition of the photonic nanojet (PNJ). This framework resolves longstanding ambiguities in measuring PNJ dimens…
