For two port system, I successfully get the time domian plot with smooth pulse as input.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/28-10-2024-1730156303-mceclip2.png\" width=\"558\" height=\"226\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;Now I want to calculate the electromagnetic field around the antenna to calculate the time response of electromagnetic field depends on the input signal. I try to make a near field radiation as I did for other non transient analysis, but when I change the solution type to transient, near field radiation menu is deactivated. I guess there is some restriction for transient analysis to make a near field data extraction but I want to make sure it is really impossible to do it.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/28-10-2024-1730156272-mceclip1.png\" width=\"298\" height=\"130\" \/>&lt;\/p&gt;&lt;p&gt;&nbsp;I know the electric field plot by the save field option for analysis setup can give me the overall distribution, but I want to obtain EB field time series in exact location.&lt;\/p&gt;&lt;p&gt;<img loading=\"lazy\" decoding=\"async\" src=\"https:\/\/innovationspace.ansys.com\/forum\/wp-content\/uploads\/sites\/2\/2024\/10\/28-10-2024-1730156351-mceclip3.png\" width=\"341\" height=\"320\" \/>&lt;\/p&gt;&lt;p&gt;Also, is there a recommended way to obtain the impulse response of antenna to electro magnetic field? or between two ports?
