Field Detail

ak

private double ak

The product of the length of the antenna and the wavenumber divided by 2. This is also the product of pi times the length of the antenna divided by the wavelength. For a "resonant antenna" the wavelength is twice the length of the antenna and ak is pi/2.

k

private double k

The wavenumber of the radiation (the wavelength is 2 pi/k).

w

private double w

The angular frequency of the radiation (the period is 2 pi/w).

t

public double t

The time.

quarterWaveAntenna

private ElectricAntenna quarterWaveAntenna

Constructor Detail

ElectricAntennaExperiment

                                 double w)

constructor for linear antenna experiment

Parameters:

k - The wavenumber of the radiation, that is, 2 pi / wavelength.

ak - The product of pi times the length of the antenna divided by the wavelength of the readiation.

w - The angular frequencey of the radiation.

Method Detail

ConstructEMSource

public void ConstructEMSource()

getHue

public double getHue(double TargetHue,
                     Vec3 r,
                     Vec RegionColor)

Method to find the hue in a given region when we are coloring according to region (Color Mode 4).

Specified by:

getHue in class BaseExperiment

Parameters:

TargetHue - This is the target hue from the renderer.

r - This is the vector postion of the point in the image.

RegionColor - This is the varous hues for the regions.
