1-10 of 2,548 results for "using simulation joint time frequency domain analysis to evaluate absorber lossy material performance in resonant cavities"

Comparing the effectiveness of different absorber/lossy materials as a function of frequency can be difficult and prone to misunderstanding when the reduction in field strength is observed directly. Often these materials are used in...

Spectral properties of the electroencephalogram (EEG) are commonly analyzed to characterize the brain's oscillatory properties in basic science and clinical neuroscience studies. The spectrum is a function that describes power as a function of frequency. To date...

Time-frequency analysis can reveal local variations and allow for separation of phase and amplitude information of nonstationary seismic waveforms. Seismic signals are used since long as a robust tool for inversion of underground structures, as has been the practice...

The rapid discharge of DC-link capacitor of the voltage source converter (VSC) based DC system is the primary indication of the fault condition. Apart from the time-domain analysis, frequency-domain analysis of fault current could also be utilized for DC...

This paper presents a pre-correlation interference detection method based on statistical analysis in the timefrequency (TF) domain for global navigation satellite system (GNSS) signals. In particular, the short time Fourier transform (STFT) is considered as the TF...

Single carrier frequency-domain turbo equalization (SC-FDTE) has gained widespread adoption in the emerging broadband spatial modulation (SM) systems operating in frequency selective channels, where the channel model considered is a quasi-static Rayleigh fading...

Single-molecule localization methods play a vital role in localization-based super-resolution fluorescence microscopy. However, it is difficult for conventional localization schemes based on Gaussian fitting to locate overlapped high-density fluorescent emitters. Currently, in...

Omnidirectional or phased-array antenna is usually adopted in the time reversal literature, but it cannot focus the power of the transmitted signals in both time- and space-domains. In this paper, we propose the hybridization of time reversal and...

SLAC developed ACE3P code suite is a comprehensive set of parallel finite-element codes for multi-physics modeling of particle accelerators. Running on massively parallel computer platforms for high fidelity and high accuracy simulation, ACE3P enables rapid virtual prototyping of accelerator...

When a fault occurs in the high-temperature superconducting (HTS) cable, a fault current consisting of extremely high frequency components is generated and propagated based on the transient response of the HTS cable. Therefore, a simulation model based on high frequency...
