MXene‐Coated 3D Printed Horn Antennas for Ku Frequency Band
Advanced Materials Technologies, EarlyView.An additive manufacturing approach to 3D printing horn antennas and coating them with Ti3C2Tx MXene is proposed. Rapid fabrication of lightweight, high‐performance antennas operating in the Ku‐band (12.4–18 GHz) has been demonstrated. The MXene‐coated antennas exhibit comparable electromagnetic performance to conventional, costly aluminum ones, with ...

RVSNUpy: A Python Package for Spectroscopic Redshift Measurement Based on Cross Correlation
The Astronomical JournalWe introduce RVSNUpy , a new Python package designed to measure spectroscopic redshifts. Based on inverse-variance-weighted cross correlation, RVSNUpy determines redshifts by comparing observed spectra with various rest-frame template spectra.
