Leaky-wave Coil Element with Improved Tx-efficiency for 7 T MRI Using a Non-Uniform Current Design
K. Popova, R. Balafenidev, J. T. Svejda +6
Imaging of the human body at ultra-high fields (static magnetic field B0>7 Tesla) is challenging due to the radio-frequency field inhomogeneities in the human body tissues caused b…
The Importance of Subcellular Structures to the Modeling of Biological Cells in the Context of Computational Bioelectromagnetics Simulations
Kevin Jerbic, Jan Taro Svejda, Benedikt Sievert +3
Numerical investigation of the interaction of electromagnetic fields with eukaryotic cells requires specifically adapted computer models. Virtual microdosimetry, used to investigat…
Particle Size-Dependent Onset of the Quantum Regime in Ideal Dimers of Gold Nanospheres
Jesil Jose, Ludmilla Schumacher, Mandana Jalali +3
We report on the nanoparticle-size-dependent onset of quantum tunneling of electrons across the sub-nanometer gaps in three different sizes (30, 50, and 80 nm) of highly uniform go…
Beam Divergence Reduction of Vortex Waves with a Tailored Lens and a Tailored Reflector
M. Haj Hassan, B. Sievert, J. T. Svejda +6
In this paper, we present a tailored lens and a tailored reflector in order to reduce the large beam divergence inherent to Orbital Angular Momentum waves (OAM waves-Vortex waves)…
Limits of effective material properties in the context of an electromagnetic tissue model
Kevin Jerbic, Kevin Neumann, Jan Taro Svejda +3
Most calibration schemes for reflection-based tissue spectroscopy in the mm-wave/THz-frequency range are based on homogenized, frequency-dependent tissue models where macroscopic m…
A Self-Matched Leaky-Wave Antenna for Ultrahigh-Field MRI with Low SAR
G. Solomakha, J. T. Svejda, C. van Leeuwen +4
The technology of magnetic resonance imaging is developing towards higher magnetic fields to improve resolution and contrast. However, whole-body imaging at 7 T or even higher fiel…
Deuteron frozen spin polarized target for nd experiements at the VdG accelerator of Charles University
N. S. Borisov, N. A. Bazhanov, A. A. Belyaev +19
A frozen spin polarized deuteron target cooled by the 3He/4He dilution refrigerator is described. Fully deuterated 1,2-propanediol was used as a target material. Deuteron vector po…
Measurement of spin-dependent total cross-section difference in neutron-proton scattering at 16 MeV
J. Broz, J. Cerny, Z. Dolezal +15
A new measurement of for polarized neutrons transmitted through a polarized proton target at 16.2 MeV has been made. A polarized neutron beam was obtained from the $^{3}\rm{…
