Reflectionless bandpass filter with flat passband, high selectivity, and enhanced out-of-band suppression

Tongxin xuebao
Currently, the design of reflectionless filters was challenged by insufficient selectivity and insufficient flatness. Therefore, a two-port microstrip reflectionless bandpass filter topology was proposed to provide a reference for addressing these ...

Using U‐Nets to Predict the Effects of Head Motion on Simulated Specific Absorption Rate for Ultra‐High Field Magnetic Resonance Imaging With Parallel Transmission

Magnetic Resonance in Medicine, Volume 96, Issue 2, Page 650-665, August 2026.
ABSTRACT Purpose Ultrahigh‐field MRI requires careful management of the specific absorption rate (SAR), which is subject and subject‐position dependent. Within‐scan subject motion may exacerbate local SAR exposure, necessitating large safety margins to prevent SAR underestimation, which hampers imaging performance.
