Extracting Power flux density in W/m2 from Postfeko using Lua script

saurav2002

Hi Community,

I am writing a lua script to extract power flux density (PFD) from postfeko. Below is the metadata of the nearfield data using Getdata() function.

DataSet:

Number of axes = 2

Frequency axis spanning from XX Hz to YY Hz with n values.

Number of quantities = 7

EFieldComp1 is a Complex with the unit V/m

EFieldComp2 is a Complex with the unit V/m

EFieldComp3 is a Complex with the unit V/m

HFieldComp1 is a Complex with the unit A/m

HFieldComp2 is a Complex with the unit A/m

HFieldComp3 is a Complex with the unit A/m

MediumIndex is a Scalar with no unit

MetaData

Using the above metadata, I was able to extract Ex, Ey, Ez, Hx, Hy and Hz.

ChatGPT gave me the following method to calculate PFD from E-field and H-field as:

Where H* is the conjugate of H-field.

I used the above formula and compared against the values shown in postfeko GUI, the values didn’t match.

Can you please advise?

Thanks!
