1. Separating the real and imaginary parts of the complex dielectric permittivity yields: 2. In which the imaginary parts offset each other leaving a real-valued expression. 3. The real and imaginary parts of \ gamma can be computed as 4. The entries of the corresponding eigenvectors therefore may also have non-zero imaginary parts . 5. Capacitive admittances have positive imaginary parts and inductive admittances have negative imaginary parts . 6. Complex samples of real-valued sinusoids have zero-valued imaginary parts and do exhibit folding. 7. Relative permittivity is a complex-valued; its real and imaginary parts are denoted as: 8. The real part of a complex number is, and its imaginary part is. 9. In this approach, \ psi is either the real or imaginary part of: 10. The imaginary part of a response function describes how a system driving force.
