The object of study - an all-dielectric planar metamaterial. The aim of the work is experimental research an all-dielectric planar metamaterial (MTM) in the subterahertz band (53,57-78,33 GHz). One of the promising trends in the development of the element base of the terahertz range is the development of new planar metamaterial (MTM), which have a defined resonant property. The design and fabrication process of all-dielectric planar MTM were developed. The geometry selection of MTM was carried out on the theoretical calculation of its resonance properties. For this purpose it was used the theory of pseudo-spectral method in the time domain, which was developed in the RI NASU. The test samples of MTM were prepared by diamond cutting. The experimental technique for the transmission and reflection coefficients measurement of MTM was developed. The experimental technique tested on laboratory developed quasi-optical systems. The quasi-optical systems consist from the set of quasi-optical devices developed in IRE NAS of Ukraine on the basis of hollow dielectric beamguide (HDB) with a diameter of 40 mm. The amplitude-frequency characteristic of the reflection and transmission waves through the planar MTM was studied. The experimental results and calculations were compared. The magnetic and electric dipole resonances were revealed in the developed samples of metamaterials. Product Description popup.authors Безбородов В.І Бойко В.Т. Косяк О.С. Кулешов Є.М. Мізрахі С.В.
