MEEP colormap for Matlab

I have been thinking of using the colormap used in the MEEP software (an open source FDTD code) as a nice alternative to the classical Matlab colormap. Here is the short Matlab code to generate it and the resulting images:

mincolor    = [1 0 0]; % red
mediancolor = [1 1 1]; % white   
maxcolor    = [0 0 1]; % blue      

ColorMapSize = 4;
int1 = zeros(ColorMapSize,3); 
int2 = zeros(ColorMapSize,3);
for k=1:3
    int1(:,k) = linspace(mincolor(k), mediancolor(k), ColorMapSize);
    int2(:,k) = linspace(mediancolor(k), maxcolor(k), ColorMapSize);
end
meep = [int1(1:end-1,:); int2];

colormap(meep); 
colorbar

MEEP colormap with ColorMapSize 16	MEEP colormap with ColorMapSize 4

*Images are snapshots from the FDTD simulation of a dish antenna.

Dish Antenna Animation (Parabolic reflector)

Finite-difference time-domain (FDTD) simulation of a parabolic reflector antenna in the transmitting phase. Reflector antennas are frequency-independent antennas and they are highly directive. As long as the source is located at the focal point, the reflected field travels in the broadside direction. In this simulation, two short pulses - first one at central frequency of 100 MHz and the other at 200 MHz are fired from the focal point (VHF regime). f/D (focal length/diameter) ratio is 0.257.

Normally, the feed antenna is also chosen to be directive, but for the purpose of illustration, we have chosen a point source as the feed antenna.

Below, one can see several microwave link stations in the form of dish antennas (Photo captured in Mount Hood in Oregon around 7000 ft).
