Utilization of anisotropic metamaterial layers in waveguide miniaturization and transitions

Ozgun, Ozlem
Kuzuoğlu, Mustafa
We introduce a new approach which enables a waveguide to support propagation of electromagnetic waves below the cutoff frequency, as well as which avoids undesirable reflections in a waveguide. These are achieved through the usage of an anisotropic metamaterial layer by employing the concept of coordinate transformation. The proposed method can be utilized for the fabrication of miniaturized waveguides, and for the elimination of discontinuities in abrupt waveguide transitions. We demonstrate some numerical experiments for finite element simulations of parallel-plate and dielectric slab waveguides.


High Conversion Efficiency InP/InGaAs Strained Quantum Well Infrared Photodetector Focal Plane Array With 9.7 mu m Cut-Off for High-Speed Thermal Imaging
Eker, Suleyman Umut; Arslan, Yetkin; Onuk, Ahmet Emre; Beşikci, Cengiz (Institute of Electrical and Electronics Engineers (IEEE), 2010-02-01)
InP/InGaAs material system is an alternative to AlGaAs/GaAs for long wavelength quantum well infrared photodetectors (QWIPs). We demonstrate a large format (640 x 512) QWIP focal plane array (FPA) constructed with the strained InP/InGaAs material system. The strain introduced to the structure through utilization of In0.48Ga0.52As (instead of In0.53Ga0.47As) as the quantum well material shifts the cut-off wavelength from similar to 8.5 to 9.7 mu m. The FPA fabricated with the 40-well epilayer structure yield...
The electronic structure of a quantum well under an applied electric field
Sari, H; Ergun, Y; Sokmen, I; Tomak, Mehmet (Elsevier BV, 1996-01-01)
The effects of an applied electric field on quantum well subband energies are calculated variationally within the effective mass approximation for model potential profiles. The concept of a quasi-bound state is examined critically. For higher electric field values it is shown that the quasi-bound state approximation for the ground and first excited state of the electron, and for the ground state of the hole is valid.

Extension of forward-backward method with DFT-based acceleration algorithm for the efficient analysis of large periodic arrays with arbitrary boundaries
Aydın Çivi, Hatice Özlem; Chou, HT (Wiley, 2005-11-05)
An extension of the discrete Fourier transform (DFT)-based forward-backward algorithm is developed using the virtual-element approach to provide a fast and accurate analysis of electromagnetic radiation/scattering front electrically large, planar, periodic, finite (phased) arrays with arbitrary boundaries. Both the computational complexity and storage requirements of this approach are O(N-tot) (N-tot is the total number of unknowns). The numerical results for both printed and freestanding dipole array's wit...
Identification of electromagnetic scattering mechanisms by two dimensional windowed fourier transform approach
Germeç, K. Egemen; Kuzuoğlu, Mustafa; Department of Electrical and Electronics Engineering (2004)
In this thesis, it is demonstrated that the two-dimensional Windowed Fourier Transform (WFT) can be effectively used to analyze the local spectral characteristics of electromagnetic scattering signals in the two-dimensional spatial frequency domain. The WFT is the extension of the Short Time Fourier Transform (STFT), which was originally derived to analyze the local spectral characteristics of one dimensional time functions. Since the WFT focuses on the local spectral behavior of the scattered field, the si...
Efficient finite element solution of low-frequency scattering problems via anisotropic metamaterial layers
Ozgun, Ozlern; Kuzuoğlu, Mustafa (Wiley, 2008-03-01)
We introduce a new technique which remedies the drawbacks in the Finite Element solution of low-frequency electromagnetic scattering problems, through the usage of an anisotropic metamaterial layer which is designed by employing the coordinate transformation approach. The usual finite element method should utilize a "challenging" mesh generation scheme to accurately simulate the "small" objects in scattering problems; on the contrary, the proposed technique provides a considerable reduction in the number of...
