A Hippocampal-Entorhinal Cortex Neuronal Network for Dynamical Mechanisms of Epileptic Seizure

IEEE Transactions on Neural Systems and Rehabilitation Engineering, 2023
Temporal lobe epilepsy (TLE) is thought to be associated with neuronal hyperexcitability in the hippocampal-entorhinal cortical (EC) circuit. Due to the complexity of the hippocampal-EC network connections, the biophysical mechanisms of the different ...

Circuit Model Analysis of Switchable Perfect Absorption/Reflection in an Active Frequency Selective Surface

IEEE Access, 2019
This paper presents a switchable perfect absorber/reflector in S band using a PIN diode integrated active frequency selective surface (AFSS). It is numerically demonstrated that the AFSS shows over 99% absorptivity at 3.5 GHz when the diode is forward ...
