Calibration‐Free GRAPE pTx Pulses for Homogeneous Spatial‐Selective Excitation at 7T
Magnetic Resonance in Medicine, Volume 95, Issue 6, Page 3104-3115, June 2026.ABSTRACT Purpose Extend the universal pulse GRAPE formalism to pulses with a defined spectral response, and apply the concept to spatial selection. Methods We added Bloch simulations at several frequencies for each voxel to the pulse calculation to create universal spectrally‐selective GRAPE pulses.

New High Precision Measurements of Apollo Samples: 0.3–5 GHz Complex Refractive Indices
Journal of Geophysical Research: Planets, Volume 131, Issue 6, June 2026.Abstract Active and passive radar techniques provide information on the subsurface structure and history of planetary bodies. However, interpretations of radar data are limited by our understanding of the complex dielectric permittivity and magnetic permeability of the surface material.
