Dear Didier, In addition to my question about discontinuity in fields in my previous message, I have two more questions about the structure of the 1D FIELD_MAP file. (1) What does the number in the 2nd row represent (in Jonathan's example it is "1")? (2) Can the field data be unevenly spaced? I trie...

Dear Didier, Following your example, in the case that: DRIFT 10 30 FIELD_MAP 100 .1 -90 30 1 1 0 0 test DRIFT 10 30 There is a discontinuity in the field at z = 10 mm and 10.1 mm. Would that be fine? In practice, should the data in FIELD_MAP smoothly goes to zero at the beginning and the end? Best r...

Jonathan, Didier,

Thanks a lot.
In case of the FIELD_MAP does not reach zero within the its length, how does TraceWin handle it?

Best regards,

Hello, I believe a gap, and other RF components, is excited by a sinusoidal source by default. Can a RF component be excited by a multi-frequency source or non-sinusoidal source? Please show it in the example below. ; Structure file freq 300 DRIFT 0 100 drift 100 10 gap 100e3 30 10 0 drift 100 10; D...
