Hybrid data fidelity term approach for quantitative susceptibility mapping. [PDF]
Magn Reson Med, 2022 Purpose Susceptibility maps are usually derived from local magnetic field estimations by minimizing a functional composed of a data consistency term and a regularization term. The data‐consistency term measures the difference between the desired solution and the measured data using typically the L2‐norm.

3D Acoustofluidics via Sub‐Wavelength Micro‐Resonators
Advanced Functional Materials, Volume 33, Issue 9, February 23, 2023., 2023 3D acoustofluidic micro‐resonators are demonstrated, which are used to generate highly localized and complex acoustic fields. This 3D concept is unique compared to more conventional planar actuation systems, expanding the range of acoustic fields and acoustic patterns that can be produced. This micro‐resonator concept accordingly yields high‐magnitude,

A simple cavity method which increases bandwidth of cylindrical dipole antennas to almost 100%
IET Microwaves, Antennas &Propagation, Volume 16, Issue 8, Page 526-536, July 2022., 2022 Abstract A broadband dipole antenna and an integrated cavity section responsible for increasing bandwidth are introduced, designed, and successfully fabricated. This simple and highly effective cavity is added at the dipoles input, where the concentric coaxial feed line becomes its inner conductor, and the dipoles cylinder becomes its outer conductor ...
