    Finite element modeling of double-tip diffraction
    (Institute of Electrical and Electronics Engineers Inc., 2015) Ozgun,O.; Sevgi,L.
    Finite element (FEM) diffraction modeling of double-tip structure is presented and its accuracy is compared with the uniform theory of diffraction (UTD) and the method of moments (MoM). The locally-conformal perfectly matched layer (PML) approach is utilized to truncate the infinitely-long structure in a finite-sized computational domain. Diffracted field is obtained by using a four-step procedure which extracts the diffracted field from scattered field. Numerical results are demonstrated. © 2015 IEEE.

    Parabolic equation toolbox for radio wave propagation
    (Institute of Electrical and Electronics Engineers Inc., 2015) Ozgun,O.; Apaydin,G.; Kuzuoglu,M.; Sevgi,L.
    A parabolic equation toolbox (called PETOOL) has been developed in MATLAB with a user-friendly Graphical User Interface (GUI) for modeling radio-wave propagation over variable terrain and through homogeneous and inhomogeneous atmosphere (O. Ozgun, G. Apaydin, M. Kuzuoglu, L. Sevgi, Computer Physics Communications, 182, 2638-2654, 2011). The unique feature of the toolbox is that it implements both one-way and two-way Fourier split-step method to take account of both forward and backward propagating waves over variable terrain. © 2015 IEEE.
