Member Function Documentation

Fourier()

static void Fourier ( ComplexAmplitude  ca )

static

Computes the Fourier Transform of the given ComplexAmplitude. The ComplexAmplitude ca is changed during the Fourier Transform.

Parameters

ca	ComplexAmplitude to be transformed.

Fourier_Physical()

static void Fourier_Physical ( ComplexAmplitude  ca )

static

Computes the Physical Fourier Transform of the given ComplexAmplitude. The ComplexAmplitude ca is changed during the Fourier Transform.

Parameters

ca	ComplexAmplitude to be transformed.

FourierTransformation()

static HarmonicFieldsSet FourierTransformation ( HarmonicFieldsSet  hfs, bool  useInverseTransformation = false, bool  useNumericalTransformation = false  )

static

Applies a Fourier transformation on the given Harmonic Fields Set.

Parameters

hfs	The Harmonic Fields Set to transform.
useInverseTransformation	If this optional parameter is set to true an inverse Fourier transformation is used.
useNumericalTransformation	If this optional parameter is set to true the numerical Fourier transformation instead of the physical one is used. This influences only the scaling of the resulting field.

Returns

The transformed Harmonic Fields Set.

InverseFourier()

static void InverseFourier ( ComplexAmplitude  ca )

static

Computes the inverse Fourier Transform of the given ComplexAmplitude. The ComplexAmplitude ca is changed during the Fourier Transform.

Parameters

ca	ComplexAmplitude to be transformed.

InverseFourier_Physical()

static void InverseFourier_Physical ( ComplexAmplitude  ca )

static

Computes the physical inverse Fourier Transform of the given ComplexAmplitude. The ComplexAmplitude ca is changed during the Fourier Transform.

Parameters

ca	ComplexAmplitude to be transformed.
