I would imagine current limit goes up with frequency to a level. I do recall reading it somewhere but I cannot find it now. Is there anyone who is aware of such standards?
Ashkan Latifi that could be the case. I need the number. I remember something around 250mA or something. Its not a low number.
To the best of my knowledge, there are two main safety standards for safety levels with respect to human exposure to RF EM Fields;
One guideline is standardized by INTERNATIONAL COMMISSION ON NON‐IONIZING RADIATION PROTECTION (ICNIRP) which is an European standard, I guess, that provides guidelines "FOR LIMITING EXPOSURE TO TIME‐VARYING ELECTRIC, MAGNETIC AND ELECTROMAGNETIC FIELDS (UP TO 300 GHZ)" and you can find it here:
https://www.icnirp.org/cms/upload/publications/ICNIRPemfgdl.pdf
The other one is the IEEE standard called C.95 Standard with different revisions "IEEE Standard for Safety Levels with Respect to Human Exposure to Radio Frequency Electromagnetic Fields, 3 kHz to 300 GHz". You can find the latest revision here:
https://ieeexplore.ieee.org/document/1626482
Hope it helps!
thanks Reza.
these are exposure standards. i havent seen any note on current flow in the body.
We could argue SAR has a current density term but I am after high f conduction current limits. Any thoughts?
There are threshold limits for time-varying electric field that can initiate current flow in tissue. Also, there is ranges of threshold currents for indirect effects up to 100KHz on P.11 of ICNIRP standard.
