Due to the extensive use of electromagnetic fields in everyday life, more information is required for the detection of mechanisms of interaction and the possible side effects of electromagnetic radiation on the structure and function of the organism. In this paper, we study the effects of low-power microwaves (2.45 GHz) on the membrane fluidity of rod(More)
This paper presents the design and manufacturing of millimeter wave metamaterial Composite Right / Left Handed (CRLH) devices — directional coupler and band-pass filter — on silicon substrate in coplanar waveguide (CPW) configuration. The devices were designed and simulated in a frequency band between 35 GHz–40 GHz for the band-pass(More)
The paper presents results obtained in modeling, technological fabrication and measurements for a CPW (coplanar waveguide) zeroth-order resonating antenna, based on CRLH TL (composite right/left-handed transmission line). The CRLH TL consists of cascaded cells of series CPW interdigital capacitors and parallel CPWs. The antenna was fabricated on silicon(More)
