A hybrid method to calculate mutual coupling of electric or magnetic current elements on a cylindrically layered structure using MoM is presented. For the calculation of the MoM matrix entries, when rho = rho', if phi is not close to phi', the closed-form Greenpsilas functions are employed. When phi is close to phi', since the spectral-domain Greenpsilas functions do not converge, MoM matrix elements are calculated in the spectral domain. The technique is applied to both microstriplines and slots placed on a layered cylindrical structure. The computational efficiency of the analysis of mutual coupling of printed elements on a cylindrically layered structure is increased with the use of proposed hybrid method due to use of closed-form Greenpsilas functions. Beside the presented geometries used in the analysis, multilayer coupling geometries such as slot-coupled microstrip patch antennas and slot antenna with microstrip feeding can also be analyzed.

Mutual coupling of printed elements on a cylindrically layered structure using closed-form Green's functions Acar, R. C.; Dural, G. (EMW Publishing, 2008-01-01) A hybrid method to calculate mutual coupling of electric or magnetic current elements on a cylindrically layered structure using closed-form Green's functions is presented. When rho = rho' and phi is not very close to phi', closed-form Green's functions are employed in the calculation of MoM matrix entries. When both rho = rho' and phi = phi', series representation of the spectral domain Green's functions do not converge, therefore closed-form Green's functions can not be employed. In that case MoM matrix e...
Singularity Cancellation for Accurate MoM Analysis of Periodic Planar Structures in Layered Media Adanir, Suleyman; Alatan, Lale (Institute of Electrical and Electronics Engineers (IEEE), 2020-08-01) One of the singularity cancellation schemes proposed in the literature is applied to calculate singular integrals arising in the method of moments (MoM) analysis of 2-D periodic planar structures in multilayered media. Discrete complex image method is utilized for the accurate approximation of Green's function which also makes possible the application of the Ewald transformation for the efficient computation of the series associated with the periodic structure. This approximation and transformation modifies...
Hybrid connection of RF MEMS and SMT components in an impedance tuner Unlu, Mehmet; Topalli, Kagan; Atasoy, Halil Ibrahim; Demir, Şimşek; Aydın Çivi, Hatice Özlem; Akın, Tayfun (Elsevier BV, 2010-01-01) This paper presents a systematic construction of a model for a hybrid connected RF MEMS and SMT components in a reconfigurable impedance tuner. The double stub hybrid impedance tuner which employs a high number of MEMS switches is selected to demonstrate the feasibility of the connections. In the hybrid tuner, MEMS switches are actuated with DC bias signals, where SMT resistors de-couple RF from the DC lines. The hybrid tuner is realized in two steps, where the MEMS impedance tuner is fabricated on a glass ...
Closed-form Green's functions for cylindrically stratified media Tokgoz, C; Dural Ünver, Mevlüde Gülbin (2000-01-01) A numerically efficient technique is developed to obtain the spatial-domain closed-form Green's functions of the electric and magnetic fields due to z- and phi-oriented electric and magnetic sources embedded in an arbitrary layer of a cylindrical stratified medium. First, the electric- and magnetic-field components representing the coupled TM and TE modes are derived in the spectral domain for an arbitrary observation layer The spectral-domain Green's functions are then obtained and approximated in terms of...
Performance evaluation of magnetic flux density based magnetic resonance electrical impedance tomography reconstruction algorithms Eker, Gökhan; Eyüboğlu, Behçet Murat; Department of Electrical and Electronics Engineering (2009) Magnetic Resonance Electrical Impedance Tomography (MREIT) reconstructs images of electrical conductivity distribution based on magnetic flux density (B) measurements. Magnetic flux density is generated by an externally applied current on the object and measured by a Magnetic Resonance Imaging (MRI) scanner. With the measured data and peripheral voltage measurements, the conductivity distribution of the object can be reconstructed. There are two types of reconstruction algorithms. First type uses current de...
