2010-05-04 Thread Nizamov Shawkat
Hi! Stepped frequency continuous wave, as you describe it, seems inpractical for me. Any coarse frequency change will cause high harmonics wave, which may lead to numerous artifacts. Even using very small frequency steps you should still make sure that any such change will not cause abrupt change

[Meep-discuss] nature of pulses from a Gaussian source

2010-05-04 Thread Sanchit Khatavkar
Dear Prof.Steven and meep users, I just wanted to know what are the pulses that a gaussian source outputs. Are those temporal pulses? The input that we give to the source is a frequency spread. Can this be used to model pulses in the time domain? Say femtosecond pulses? Thanks, Sanchit

Hi, I want to simulate a doppler radar in meep. I would like to how I could give motion (uniform or radial motion in real-time) to an object in meep. So, the scenario I am trying to simulate will be as follows: an antenna will send some pulses for a certain time and along the frontal view of the an

[Meep-discuss] SFCW (Stepped frequency continuous wave) source in meep

2010-05-04 Thread Shravan S
Hi, I am interested in simulating an SFCW (Stepped frequency continuous wave) source in meep. So, for every interval of time, the frequency of the transmitted signal changes by a small value delta_f. The number of intervals go up to 400 or even 4000, so specifying a start time and end time for each
