(number) The (real) frequency of the excitation.
The algorithm combines second-order accuracy in the real frequency with third-order user-adjustable attenuation.
The significant increase in real frequency of whistler waves can be observed.
As a final test, we also successfully verified that our experiment reproduces the real frequency shift which modes experience when passing the vicinity of the EP.
Both the amplitude response and phase response are real-valued functions of (real) frequency, while the frequency response is the complex function of frequency given by.
The model has been tested extensively for sound-wave propagation, the collisionless (universal mode) drift wave real frequency and growth rate, the ηi-mode real frequency and growth rate, and the fluctuation spectrum has been elucidated.
The new design procedure is based on the two-variable description of the Simplified Real Frequency Technique.
The method is based on combining the simplifield real frequency technique with the algebraic network decomposition by Fettweis.
Analytical expressions for growth rate and real frequency of whistlers propagating parallel to magnetic field direction are attained.
These waves, which have a real frequency, are calculated using a time-evolution algorithm that includes flow effects.
In particular, experiments on parity-time symmetric systems15,16, for which the EPs occur on the real frequency axis, have been a driving force behind recent progress17,18,19,20,21,22,23,24.
