Harmonic analysis based on time domain mutual-multiplication window

open access: yesJournal of Modern Power Systems and Clean Energy, 2016
The signal spectral leakage and fence effect are prone to take place during the power harmonic analysis by fast fourier transform (FFT) under asynchronous sampling. The inhibiting ability of classical window functions is restricted by side-lobe behaviors.

Fast finite difference time domain analysis of microstrip patch antennas [PDF]

open access: yes, 1991
Although the finite-difference-time-domain method has been successfully used to model microstrip-fed patch antennas, this has been achieved using uniform grids.

On the Time Domain Error Caused By the Frequency Domain Sampling Rate in a Reverberation Chamber

open access: yesIEEE Access, 2019
The time domain (TD) response of a reverberation chamber (RC) can be obtained from the inverse Fourier transform of the measured S-parameters in the frequency domain (FD).

Time-domain green's function-based parametric sensitivity analysis of multiconductor transmission lines [PDF]

open access: yes, 2012
We present a new parametric macromodeling technique for lossy and dispersive multiconductor transmission lines. This technique can handle multiple design parameters, such as substrate or geometrical layout features, and provide time-domain sensitivity ...

Timescale Spectra in High Energy Astrophysics [PDF]

open access: yes, 2002
A technique of timescale analysis performed directly in the time domain has been developed recently. We have applied the technique to studying rapid variabilities of hard X-rays from neutron star and black hole binaries, gamma-ray bursts and terrestrial ...

Time domain analysis of a wideband common-mode suppression filter for bent interconnects [PDF]

open access: yes, 2011
A technique to efficiently reduce differential-to-common mode conversion occuring at a bend discontinuity in coupled microstrip lines is investigated. Total signal integrity in the interconnect structure has been improved by minimizing the differential ...

Equivalence analysis of dielectric test methods in time domain and frequency domain

open access: yesInternational Journal of Electrical Power & Energy Systems
Wideband dielectric response is crucial for accurate assessment of insulation condition. However, time-domain measurements such as polarization and depolarization current (PDC) tests often lose high-frequency components, while frequency domain ...
