TE-wave propagation in a graded waveguide structure
M Dalarsson, S Nordebo
We investigate TE-wave propagation in a hollow waveguide with a graded dielectric layer, described using a hyperbolic tangent function. General formulae for the electric field comp…
A parametric model for the changes in the complex valued conductivity of a lung during tidal breathing
Sven Nordebo, Mariana Dalarsson, Davood Khodadad +8
Classical homogenization theory based on the Hashin-Shtrikman coated ellipsoids is used to model the changes in the complex valued conductivity (or admittivity) of a lung during ti…
Absorption and optimal plasmonic resonances for small ellipsoidal particles in lossy media
Mariana Dalarsson, Sven Nordebo, Daniel Sjöberg +1
A new simplified formula is derived for the absorption cross section of small dielectric ellipsoidal particles embedded in lossy media. The new expression leads directly to a close…
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…
Analytical solution for wave propagation through a graded index interface between a right-handed and a left-handed material
Mariana Dalarsson, Philippe Tassin
We have investigated the transmission and reflection properties of structures incorporating left-handed materials with graded index of refraction. We present an exact analytical so…
