| Popis: | The advancement of millimeter wave and terahertz technologies have revolutionized high speed wireless networks and precise tracking systems. These technologies offer unique penetration capabilities in specific scenarios, significantly enhancing the capability to investigation plasma. Recent breakthroughs include the precise diagnosis of plasma electron density using terahertz time domain spectroscopy and the modeling of plasma sheaths in re-entry spacecraft through scattering matrices. Concurrently, extensive research efforts have been dedicated to comprehending plasma's influence on electromagnetic wave behaviors, encompassing reflection, transmission, absorption and also phase shift. In this paper, we employ COMSOL Multiphysics software to create an inductively coupled plasma (ICP) device, enabling the simulation of various plasma density arrangements. Our investigation focuses on unraveling the intricate interplay between plasma configurations and millimeter-wave transmission characteristics. The findings underscore the substantial impact of diverse plasma concentration arrangements on the behavior of electromagnetic waves traversing through them. Additionally, these arrangements endow the plasma with a discernible degree of frequency selectivity, thus expanding our understanding of plasma behavior in novel ways.
