Non-LTE line formation for heavy elements in four very metal-poor stars
Stellar parameters and abundances of Na, Mg, Al, K, Ca, Sr, Ba, and Eu are determined for four very metal-poor stars (-2.66 < [Fe/H] < -2.15) based on non-LTE line formation and analysis of high-resolution (R ~60000 and 90000) high signal-to-noise (S/N >

Amplifier‐Based Programmable Metasurface for Bidirectional Full Polarization Enhancement
An amplifier‐based programmable metasurface is proposed to enhance bidirectional propagation of various polarized electromagnetic waves. The metasurface incorporates patch scatterers, reconfigurable phase shifters, and negative resistors to manipulate wave direction and improve wireless communication coverage. The Class‐E reflection amplifier minimizes
