In this article Eqs. (7) and (12) appeared incorrectly and should have been as below.

$${\varepsilon }^{*}(\omega ) = {\upepsilon}^{{{\prime}}}(\omega )-{\text{j}}{\upepsilon}^{^{\prime\prime}}(\omega )$$

(7)

$$ M^{{\prime}} = \frac{{M_{1\max }^{^{\prime\prime}} }}{{\left( {\left( {1 - \beta_{1} } \right) + \left( {\frac{{\beta_{1} }}{{1 + \beta_{1} }}} \right)} \right)\left[ {\left( {\frac{{f_{1\max } }}{f}} \right) + \left( {\left( {\frac{f}{{f_{1\max } }}} \right)^{{\beta_{1} }} } \right)} \right]}} + \frac{{M_{2\max }^{^{\prime\prime}} }}{{\left( {\left( {1 - \beta_{2} } \right) + \left( {\frac{{\beta_{2} }}{{1 + \beta_{2} }}} \right)} \right)\left[ {\left( {\frac{{f_{2\max } }}{f}} \right) + \left( {\left( {\frac{f}{{f_{2\max } }}} \right)^{{\beta_{2} }} } \right)} \right]}} $$

(12)

Moreover, there were the repetition of symbols in the text after Eq. (12). The corrected text is as below.

where M″_max is the peak maxima and f_max is their corresponding frequency.
