Detailed Description

Implement the dispersion model proposed in [Holm2011].

The constitutive relation is give by

$e_r(\omega) = \frac{1}{E_0} \frac{1+(j\omega\tau_\epsilon)^a}{1+(j\omega\tau_\sigma)^a}$

where $E_0$ denotes the DC bulk modulus, $\tau_\epsilon$ denotes the relaxiation time, $\tau_\sigma$ denotes the retardation time, and $a$ denotes the fractional exponent.

Member Function Documentation

HNAcousticProperty * HNAcousticProperty::clone ( ) const

virtual

Reimplemented from AcousticProperty.

std::complex< double > HNAcousticProperty::getAcousticImpedance ( const double freq ) const

virtual

Use the dispersion model to calculate the medium impedance.

Reimplemented from AcousticProperty.

std::complex< double > HNAcousticProperty::getAcousticWaveNumber ( const double freq ) const

virtual

Use the dipersion model to calculate the acoustic wave number.

Reimplemented from AcousticProperty.

double HNAcousticProperty::getEquivalentBulkModulus ( const double freq ) const

virtual

Returns: Return AcousticProperty::K for all frequencies. When this function is overriden in the child class, its return value is frequency dependent due to the dispersion model.

Reimplemented from AcousticProperty.

double HNAcousticProperty::getEquivalentConductivity ( const double freq ) const

virtual

Returns: Return AcousticProperty::xi for all frequencies. When this function is overriden in the child class, its return value is frequency dependent due to the dispersion model.

Reimplemented from AcousticProperty.

HNAcousticProperty & HNAcousticProperty::operator= ( const HNAcousticProperty & the_property )

void HNAcousticProperty::print ( ) const

virtual

Print the parameters associated with the material.

Reimplemented from AcousticProperty.
