Attractive method for thickness-independent permittivity measurements of solid dielectric materials
Hasar U.C.; Barroso J.J.; Bute M.; Kaya Y.; Kocadagistan M.E.; Ertugrul M. (2014)We propose a non-resonant-type method for reference-plane invariant and thickness-independent permittivity measurement of solid dielectric materials when there is no information from permittivity. To achieve this, we derive ... -
Determination of effective constitutive parameters of inhomogeneous metamaterials with bianisotropy
Hasar U.C.; Buldu G.; Kaya Y.; Ozturk G. (Institute of Electrical and Electronics Engineers Inc., 2018)A recursive algorithm is proposed to accurately extract the electromagnetic parameters of isotropic/bianisotropic metamaterial (MM) slabs of inhomogeneous structures. The algorithm is based on the recursive calculations ... -
Determination of Reference-Plane Invariant, Thickness-Independent, and Broadband Constitutive Parameters of Thin Materials
Hasar U.C.; Kaya Y.; Barroso J.J.; Ertugrul M.

New records of the water mites of the genus Axonopsis Piersig, 1893 (Acari: Hydrachnidia, Aturidae) from Siirt Province, Turkey, are presented in this paper. Two subgenera and three species are newly recorded to the Turkish ... -
New water mites of the family Hygrobatidae (Acari, Hydrachnidia) from Turkey
In this study, the findings of three water mite species of the family Hygrobatidae collected from different streams in Turkey were evaluated. Hygrobates (s. str.) anatolicus Esen & Peši?, sp. n. is described as new for ... -
Noniterative complex permittivity retrieval using calibration-independent waveguide measurements
Hasar U.C.; Kaya Y. (Elsevier B.V., 2017)Calibration-independent nonresonant measurements can be employed to eliminate the need for calibration before microwave measurements. These methods generally assume that the location of the sample in its measurement cell ... -

Reference-plane invariant transmission-reflection method for measurement of constitutive parameters of liquid materials
Hasar U.C.; Barroso J.J.; Kaya Y.; Ertugrul M.; Bute M. (2013)We propose a new transmission-reflection method for measuring constitutive parameters of liquid samples inside an asymmetric measurement cell (a sample over a low-loss holder in vertical position inside an empty waveguide ... -
Reference-Plane-Invariant Effective Thickness and Electromagnetic Property Determination of Isotropic Metamaterials Involving Boundary Effects
Hasar U.C.; Barroso J.J.; Buldu G.; Bute M.; Kaya Y.; Karacali T.; Ertugrul M. (Institute of Electrical and Electronics Engineers Inc., 2015)It is well recognized that near-field effects become dominant when the metamaterial (MM) is in resonance. In addition, any inaccurate information of the location of reference planes, and the effective length can seriously ... -
Self-Calibrating Noniterative Complex Permittivity Extraction of Thin Dielectric Samples
Hasar U.C.; Kaya Y. (Institute of Electrical and Electronics Engineers Inc., 2018)A microwave method relying on uncalibrated scattering (S-) parameters is proposed to measure the complex permittivity (?r) of thin dielectric samples. It has the following two main advantages. First, it takes into account ... -
