Probability Distribution of the Quality Factor of a Mode-Stirred Reverberation Chamber

, 2012
We derive a probability distribution, confidence intervals and statistics of the quality (Q) factor of an arbitrarily shaped mode-stirred reverberation chamber, based on ensemble distributions of the idealized random cavity field with assumed perfect ...

Inverse Fourier transform technique of measuring averaged absorption cross section in the reverberation chamber and Monte Carlo study of its uncertainty [PDF]

, 2016
The averaged absorption cross section (ACS) of a lossy object characterises its ability to capture power from diffused electromagnetic waves. The averaged ACS is very important in many EMC research areas such as indoor wireless channel modelling and ...

Neurophilic Biomimetic Lipoprotein‐Mediated Targeted Nerve Growth Factor Delivery for Traumatic Brain Injury Therapy

Advanced Science, EarlyView.
Design of neurophilic biomimetic lipoprotein for intracerebral delivery of nerve growth factor (NGF) to traumatic brain injury (TBI). Nc‐rHDL@P can cross the BBB through ApoE3‐receptors interaction and target neurons via αRDP‐nAChR interaction. Nc‐rHDL@P delivers NGF to the lesion sites, rescues neurons, curbs inflammation, boosts sensorimotor and ...

Correlation matrix methods to assess the stirring performance of electromagnetic reverberation chambers [PDF]

Wave Motion, 2019
Abstract The use of correlation matrices to evaluate the number of uncorrelated stirrer positions of electromagnetic reverberation chambers has widespread applications in electromagnetic compatibility. We present a review of recent methods based on multivariate correlation functions that relates statistical inhomogeneities in space (frequency) to the

VO2 Oscillator Circuits Optimized for Ultrafast, 100 MHz‐Range Operation

Advanced Electronic Materials, EarlyView.
The present study demonstrates ultrasmall (≈30 nm) VO2 Mott memristor‐based oscillators which enter the >100 MHz frequency range via device scaling and optimization of the circuit layout for high frequency operation. Time‐resolved investigation of switching dynamics along with circuit‐level and physics‐based electrothermal simulations identify physical
