Screenshots from the Full Wave Reflectometer simulation

 

model plasma

Plasma modeled from initial parameters, display of electron density.



compute areas

Computational grid for 50 GHz is displayed relative to electron density.  Full wave and paraxial compute regions are shown.  The antenna is on the right edge of the vacuum area.



cutoff

The O-mode cut off locations are calculated and color-coded for the frequency range.



output

The full wave solution is calculated and shown relative to the O-mode cutoff locations.



outputzoom

Zoom in view of full wave solution.



outputgraph

The intensity of the full wave solution is plotted in the graph.



outputclose

A closer look at the output of the simulation for 50 GHz.



45cutoff

The O-mode cut off locations calculated and graphed for the range of frequencies.



45solution

The compute region and full wave solution for 45 GHz.

The compute region for 45 GHz was the same as for 50 GHz.  The solution for 45 GHz cuts off farther from the center than for 50 GHz as predicted by the color-coded display of cut off locations.  The visualization of the cut off locations guides the placement of the compute regions and the choice of frequencies.


Receivers are positioned by the user.

 

Multiple runs are analyzed for coherence per receiver per frequency.

 

Each frequency received at each antenna is drawn in a separate graph.

 

R values correspond to the cut off locations of the frequencies used in the simulation.

 

The data from all the runs is analyzed for coherence.
