Computational Methods for Electromagnetics

Optimal High-Order Method of Moment combined with NURBS for the scattering by a 2D cylinder.

“…First and foremost, comparing some articles and books on propagation theory, let us note the inconsistent use of TM and TE polarization [18]. So, it is necessary to mention that the convention applied in this article is the same as used by Peterson [19] or Gibson [1] in contrast to Tsang [20] or Naqvi [18]. If the propagation vector k lies inx −ẑ plane, the TM/TE polarization refers to the electric/magnetic field being inŷ direction as shown in figure (4).…”

“…Once the surface currents have been estimated, the Radar Cross Section (RCS) of the scattered can be evaluated by a very well known integration process, see for instance [19].…”

Subspace-Based Optimization Method for Reconstructing Perfectly Electric Conductors

“…After such discretization, the method of moments (MoM) can be used to solve the forward problem [10]. The center of each PEC line-element is located at r j , j = 1, 2, .…”

“…R mj denotes the distance between the mth and jth segments which is given by R mj = |r m − r j |. When m = j, the integral is evaluated by the method described in [10]. After the surface current is obtained, the scattered field received by the antennas outside the domain is given by…”

“…Here w is the length of the line element and γ = 1.781 [10]. The scattered field is given byĒ sca =Ḡ s ·J (4)…”
