This work provides validation of Finite-Integral-Method (FIM) electromagnetic field simulations of a patch antenna for travelling wave excitation using experimental data measured in a 9.4T human MRI scanner. Quantification of the excitation field was performed with the Actual Flip angle Imaging (AFI) sequence. Good quantitative agreement is illustrated between simulation and experimental data.
