A period-ring-valued gamma function and a refinement of the reciprocity law on Stark units (Algebraic Number Theory and Related Topics 2017)

A period-ring-valued gamma function and a refinement of the reciprocity law on Stark units (Algebraic Number Theory and Related Topics 2017)
This is an announcement of the results of the paper "On a common refinement of Stark units and Gross-Stark units". We study a relation between CM-periods, multiple gamma functions, the rank one abelian Stark conjecture, and their p-adic analogues. The main results are as follows.

A coding based metasurface absorber with triple circular ring resonator for broadband RCS reduction and high EMI shielding effectiveness

Results in Engineering
In this paper, a novel coding-based metasurface absorber (CMA) featuring a triple circular ring resonator is introduced for broadband radar cross-section (RCS) reduction and high electromagnetic interference (EMI) shielding effectiveness.
