 title = {Error model for Contour-FFT evaluation of the free-space on-plane Green's function},
 author = {Gueuning, Quentin and Hubert, Simon and Craeye, Christophe and Oestges, Claude},
 abstract = {Closed-form analytical expressions are derived for the numerical integration of the spectral Green's function with Contour-FFT. Results indicates that a proper uniform grid of spatial points enhances the convergence rate of the truncation error, that the Nyquist-Shannon theorem can be generalized to inverse Laplace transforms on linear path and that the relative error specific to Contour-FFT is a regularized gamma function. Two examples illustrate the modularity of the approach.},

 title = {Unequally-spaced fast Laplace transform for Green's function evaluation},
 author = {Gueuning, Quentin and Craeye, Christophe and Oestges, Claude},
 abstract = {A fast method for the radiation analysis of arbitrary oriented planes is presented. It combines an adaptive spectral integration scheme and a recently proposed unequally-spaced fast Laplace transform algorithm. It is illustrated on the free-space Green's function through an example where an important speed-up factor is evaluated compared to the brute force spectral integration.},

 title = {Inhomogeneous plane-wave spectrum basedphysical optics},
 author = {Gueuning, Quentin and Craeye, Christophe and Oestges, Claude},
 abstract = {The Physical Optics aperture radia- tion is decomposed into an inhomogeneous plane- wave spectrum, for which a sub-nyquist sampling is achieved, despite a 2-digits accuracy. Validation with a Hertzian dipole and observations are made for large planar surfaces. The Spectral Physical Optics (SPO) seems particularly well-suited for multiple in- teractions between large facets in complex scattering environnements.},

 author = {Gueuning, Quentin and Craeye, Christophe and Raucy, Christopher},
 abstract = {Wideband arrays devoted to radio-astronomy are analyzed. The Macro Basis Functions (MBFs) approach is used and improvements on the interpolatory approach are proposed for the fast interaction between MBFs: application to wire-antennas, DFT approach for the harmonic decomposition and specific to extremely small distances between antennas.},

    @inproceedings{boreal:162276,
 title = {Mutual coupling analysis of large irregular arrays: from multipole to interpolatory methods},
 author = {Gueuning, Quentin and Craeye, Christophe},
 abstract = {A novel formulation is proposed for the multipole expansion, called Laurent series formulation. It finds applications to the fast calculations of integral reactions between Macro Basis Functions in large planar irregular arrays of identical elements. Indeed, it automatically provides the coefficients of the harmonic-polynomial model of the reactions. A better understanding is also achieved for the minimized impact of the so-called low-frequency breakdown when computing interactions at small distances with the interpolatory method.},

    @inproceedings{boreal:162280,
 title = {Validation of the HARP method for simulation ofmutual coupling between SKALA antennas},
 author = {Gueuning, Quentin and Craeye, Christophe},
 abstract = {The low-frequency instrument of the SKA radiotelescope will be made of large arrays of log-periodic antennas. Their mutual coupling may be strong and needs to be modeled in terms of em- bedded element patterns. The HARP method is based on Macro Basis Functions and computes their interactions versus relative positions, based on a lim- ited number of explicit calculations in the near eld. This paper shows results of this method in the low and medium range of the foreseen frequency spec- trum, considering the SKALA (SKA Log-Periodic Antennas) designed for this new telescope.},
