Hello, >> I want to know about difference between continuous source and Gaussian source. The main difference is that a continuous source is a wave with just one frequency and as its name says it is continuous, so it is always emitting waves(You can turn it on/off with start/end-time). The Gaussian source theoretically contains the hole spectrum of frequencies(in practical situations in meep, you choose the range of frequencies it uses with fwidth characteristic). When I say, it contains the hole spectrum I mean that it is a Gaussian wave packet centered in a frequency and extending(in frequencies) to infinity but with less intensity as you get far(again in frequency) from the central one. I suppose that was what you were asking, but sorry if it is not.
The other question... I am afraid I cannot answer, maybe someone else can. Best regards, Fco. Cordobés Aguilar.
