FDTD getting EM fields as a function of distance

  I have a student who is working on obtaining EM field intensity data for gold nanospheres. Our goal is to obtain the exponential decay profile of the EM field as it extends away from the nanoparticle surface. The student has tried visualizing the data from the field profile and field power monitors, as well as using the getelectric, getmagnetic, getdata, and getresults script commands.
  The field intensities they obtained using getelectric and getmagnetic do not follow the expected exponential decay profile. They have tried adjusting the sizes of the monitors, source, and simulation box but have been unsuccessful in trying to fix this.
  
  Another issue that they ran into is when using the getelectric and getmagnetic script commands the results are in terms of "index 1", "index 2", etc., and they are unclear about what units those are referring to.
  
  In addition, when using the getdata and getresult commands they are unable to visualize any of the data at all and are wondering which of the script commands is best to use, and how to get the data after running the commands.
