WHAMP related Doubts #76

Step 2: Describe your environment

Step 3: Describe the problem

Hello Sir, I am using WHAMP dispersion solver for plotting dispersion characteristics of Lower Hybrid Wave (LHW). I have referred Ronmark,1982 report on WHAMP and vaivads,2015 paper and I am stuck with few questions.

1] Does WHAMP plots dispersion characteristics of electrostatic waves such as LHW? 2] what should be the possible start frequency and wave vector values to give as an input? 3] The distribution function can take 10 species and the normalization is always with respect to the first component of the plasma model. Does the output (frequency, perpendicular and parallel wave vector, parallel and perpendicular growth rate, etc) are already normalized values/matrix? 4] I particularly wanted to plot dispersion characteristics of the Lower Hybrid Waves using WHAMP. But. Unable to find a single paper related to dispersion characteristics of LHW using WHAMP.

Will you please help me out with these basic doubts.

Regards, Neetasha Arya.

Also, The start frequency (InputParameters.fstart) which we give into the input.parameters in the function whamp.run should be in Hz or KHz?
