i already try put the command like that, after setting power loss density and run the
simulation, however it still cannot calculate SAR from the results
can u tell me step by step or give some notes to setting the right way to solve this
problem
thanks shahid.... i already can run the simulation
and i am using the phantom head model. after run the simulation and SAR calculation i find the result for the SAR. do u know about the relationship SAR and our antenna design because i am new for SAR
what the benefit that 10g SAR less than 2 means?
the S11 for that antenna i get is -37.56dB and after implement this antenna with SAR the S11 is -12.75dB do u know why?
well SAR is a comrehensive topic so you need to do some searhing on it but as far as your question is concerned there is world wide regulation on SAR level and every new mobile handset launched into the market has to meet SAR criteria
now for 10g SAR should be less then 2 so regulatory authority will have no objection to it
regarding ur S11 results well when u place ur antenna close to human body its input impedane changes so its matching is deteriorating as compared to free space thats why ur S11 results are not good with body
i hope i answer ur question
Hi dear Shahid,
please i'm trying to calculate the SAR values by using CST. i obtain the 3D results but i dont know how can i plot the SAR values versus to the distance (cartesian: SAR-values in Y-axis and Distance (mm) in X-axis).""D is the distance that separe the antenna to all points on X-axis into the human head model )
thanks for your help that you give on this forum.
best regards.
you need to define a line along which you are interested in finding the SAR values.
then go to postprocessing and request for SAR values along the curve
Dear shahid thank you very much for your answer. it's good now.
please can you tell me about the technics used to reduce and minimize the SAR (if you have somme article please to send it to me, or post it here).my e-mail: simotic@yahoo.fr
i'm grateful for your help, thanks
Best regards
i'm doing reduction of SAR using metamaterial.
do u hav any idea on metamaterials??
i would to hav some articles relating to SAR too..
email: sueling_capri@hotmail.com
thanx a lot.
well to reduce SAR you need to reduce the backward radiation from the antenna.
now there are different techniques to reduce the backward radiation . if you search google i hope u will find lot of material
regarding metamaterial well you can use metamaterial (which are engineered materials having interested electromagnetic feature) to reduce SAR as they have frequency bandgaps for propagation of surface waves which are responsible for backward radiation
i hope this might give you some clue to your questions
Dear shahid
could you help me plz.you tell me how set up on this software headmodel to antenna distance.if i catch on distance 10mm so how iset up of my computer.
Added after 4 minutes:
Dear shahid
you tell me how i can built on metamaterial value is fixed or changeable you tell me or di electric constant and permeability what is the depended of criteria you tell me plz. rashedgen@yahoo.com
