+Numerical comparisons
+*********************
+
+This section presents some comparisons of models using different numerical modelling techniques.
+
+FDTD/MoM
+========
+
+The Finite-Difference Time-Domain (FDTD) technique using gprMax is compared with the Method of Moments (MoM) using the MATLAB antenna toolbox (http://uk.mathworks.com/products/antenna/).
+
+Bowtie antenna in free space
+----------------------------
+
+:download:`hertzian_dipole_fs.in <../../tests/numerical/vs_MoM_MATLAB/antenna_bowtie_fs/antenna_bowtie_fs.in>`
+
+This example considers the input impedance of a planar bowtie antenna in free space. The length and height of the bowtie are 100mm, giving a flare angle of 90$^\circ$.
+
+.. literalinclude:: ../../tests/numerical/vs_MoM_MATLAB/antenna_bowtie_fs/antenna_bowtie_fs.in
+    :language: none
+    :linenos:
+
+The MoM was created in MATLAB using the ``bowtieTriangular`` class:
+
+.. code-block:: matlab
+
+    bowtie = bowtieTriangular('Length', 0.1)
+
+Results
+-------
+
+:numref:`antenna_bowtie_fs_zin_results` shows the input impedance (resistive and reactive) for the FDTD (gprMax) and MoM (MATLAB) models.

+
+    Input impedance (resistive and reactive) of a bowtie antenna in free space using FDTD (gprMax) and MoM (MATLAB) models.
+
+The match between the FDTD and MoM solutions is generally very good.
