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. Dis...
The effect of antenna in the forward model of near field microwave imaging systems
Dalkilic, Akin; Alatan, Lale (2019-07-01)
A fast and accurate forward problem solver for near-field microwave imaging systems is developed by considering the electric field intensity as the measured quantity. Since the antenna port voltage values will be the real ...
UWB 3D Near-Field Imaging with a Sparse MIMO Antenna Array for Concealed Weapon Detection
Anadol, Erman; Seker, Ilgin; Camlica, Sedat; Topbas, Tankut Oguz; Koç, Seyit Sencer; Alatan, Lale; Öktem, Sevinç Figen; Aydın Çivi, Hatice Özlem (2018-04-18)
An ultra-wide-band (UWB) multiple-input multiple-output (MIMO) radar with a sparse array is designed and manufactured for three-dimensional near-field imaging applications such as concealed weapon detection. Contrary to ex...
An application of singularity cancellation for periodic structures in free space
Adanir, Süleyman; Alatan, Lale (IET; 2018-01-01)
A singularity problem arises in the computation of MoM matrix entries. Several singularity cancellation schemes are proposed in literature. One of these singularity cancellation methods is applied to handle the singularity...
