A calibration-free method for extraction of electromagnetic properties of magnetically coupled anisotropic biaxial metamaterial (MM) slabs from waveguide measurements is proposed. It relies on three measurement steps (thru, empty line, and the same line arbitrarily loaded by the MM slab) to extract electromagnetic properties. It is evaluated against another calibration-dependent method for retrieval of electromagnetic properties of a MM slab constructed by C-shaped resonators. From evaluation analysis, we note that our method, as compared to the calibration-dependent method, not only accurately extracts electromagnetic properties without requiring the use of expensive calibration standards but also is reference-invariant.

Constitutive parameters determination of bi-anisotropic metamaterials using a waveguide method HASAR, UĞUR CEM; BUTE, MUSA; Muratoğlu, Abdurrahim; BAROSSO, JOSE JOAQUIM; KARACALI, TEVHİT; ERTUĞRUL, MEHMET (2016-01-04) A retrieval method is proposed for determination of electromagnetic properties of bi-anisotropic metamaterial (MM) slabs inserted in a waveguide. For this goal, forward and backward reflection and transmission scattering (S-) parameters of a configuration where the slab is positioned into a waveguide are first derived and then a procedure for extraction of electromagnetic properties of this slab is presented. We performed full-wave electromagnetic simulations on the bi-anisotropic MM slab with split-ring-re...
Numerical analysis of long wavelength infrared HgCdTe photodiodes Kocer, H.; Arslan, Y.; Beşikci, Cengiz (2012-01-01) We present a detailed investigation of the performance limiting factors of long and very long wavelength infrared (LWIR and VLWIR) p on n Hg1-xCdxTe detectors through numerical simulations at 77 K incorporating all considerable generation-recombination (G-R) mechanisms including trap assisted tunneling (TAT), Shockley-Read-Hall (SRH), Auger and radiative processes. The results identify the relative strengths of the dark current generation mechanisms by numerically extracting the contribution of each G-R mec...
Optical characterization of Ga2SeS layered crystals by transmission, reflection and ellipsometry IŞIK, MEHMET; Hasanlı, Nızamı (2015-07-10) Optical properties of Ga2SeS crystals grown by Bridgman method were investigated by transmission, reflection and ellipsometry measurements. Analysis of the transmission and reflection measurements performed in the wavelength range of 400-1100 nm at room temperature indicated the presence of indirect and direct transitions with 2.28 eV and 2.38 eV band gap energies. Ellipsometry measurements were carried out in the 1.2-6.0 eV spectral region to get information about optical constants, real and imaginary part...
Assessment of shielding effectiveness by using electromagnetic topology method Yaşlak, Halil İbrahim; Demir, Şimşek; Department of Electrical and Electronics Engineering (2013) In this thesis, determination of the shielding effectiveness of a rectangular shielding box with apertures on its walls by using electromagnetic topology (EMT) technique based on Baum-Liu-Tesche (BLT) equation is presented. The presented technique is applied to determine the field penetration into various rectangular shielding boxes with different sizes and aperture dimensions. An HP branded computer case is also analysed as a rectangular shielding box with a CD driver slot as an aperture. Results on electr...
Practical Realization of Magnetic Resonance Conductivity Tensor Imaging (MRCTI) DEĞİRMENCİ, EVREN; Eyüboğlu, Behçet Murat (2013-03-01) Magnetic resonance conductivity tensor imaging (MRCTI) is an emerging modality which reconstructs images of anisotropic conductivity distribution within a volume conductor. Images are reconstructed based on magnetic flux density distribution induced by an externally applied probing current, together with a resultant surface potential value. The induced magnetic flux density distribution is measured using magnetic resonance current density imaging techniques. In this study, MRCTI data acquisition is experime...
