In For part B of the example, open the *.out file and find the section "DATA OF THE VOLTAGE SOURCE NO. 1". Please provide the magnitude of the current in mA. Please round the answer to nearest mA, for example 20. 

For the above exercise I am getting value of 15.8 by rounding off it will be 16 but the answer is incorrect. I followed the correct steps of video. In the current distribution section, after following the steps I found that it is different surface current than the video shown. means the pattern which I am getting in my design is different from the pattern of surface current in the video

    Please attach your cfx file.

    @mel In the last video of Topic 6 at time 7:15 the reflection coefficient shown in the video is more than -35 dB and in my case when I plot the cartesian graph for voltagesource1 i got s11 only -25 dB. Please tell what is the reason and does it affect in exercise ?? I have followed all steps correctly

    Part B is solved only for a single frequency of 300 MHz. It is shown in the image on the bottom right of the slide and mentioned in the narration. Unfortunately, the bullet point number 6 was omitted in the video. We will update the video. 

    If I solve your model at 300 MHz the correct magnitude for the answer is obtained in the OUT file.

    See below updated slide.
