On the optical theorem and optimal extinction, scattering and absorption in lossy media
Sven Nordebo, Mats Gustafsson, Yevhen Ivanenko
This paper reformulates and extends some recent analytical results concerning a new optical theorem and the associated physical bounds on absorption in lossy media. The analysis is…
Optical theorems and physical bounds on absorption in lossy media
Yevhen Ivanenko, Mats Gustafsson, Sven Nordebo
Two different versions of an optical theorem for a scattering body embedded inside a lossy background medium are derived in this paper. The corresponding fundamental upper bounds o…
Quasi-Herglotz functions and convex optimization
Yevhen Ivanenko, Mitja Nedic, Mats Gustafsson +3
We introduce the set of quasi-Herglotz functions and demonstrate that it has properties useful in the modeling of non-passive systems. The linear space of quasi-Herglotz functions…
Fundamental bounds on transmission through periodically perforated metal screens with experimental validation
Andrei Ludvig-Osipov, Johan Lundgren, Casimir Ehrenborg +5
This paper presents a study of transmission through arrays of periodic sub-wavelength apertures. Fundamental limitations for this phenomenon are formulated as a sum rule, relating…
Passive approximation and optimization using B-splines
Yevhen Ivanenko, Mats Gustafsson, B. L. G. Jonsson +4
A passive approximation problem is formulated where the target function is an arbitrary complex valued continuous function defined on an approximation domain consisting of a finite…
On the physical limitations for radio frequency absorption in gold nanoparticle suspensions
Sven Nordebo, Mariana Dalarsson, Yevhen Ivanenko +2
This paper presents a study on the physical limitations for radio frequency absorption in gold nanoparticle suspensions. A canonical spherical geometry is considered consisting of…
