Radical TADF: Quartet‐Derived Luminescence with Dark TEMPO

Advanced Materials, EarlyView.
A new class of luminescent organic quantum materials is introduced, formed by attaching a stable radical to TADF chromophores. Due to ferromagnetic exchange coupling, a high‐spin quartet state forms upon excitation, which can thermally access a bright state.

PHEMT transistor models for accurate CAD of MMIC amplifier

Journal of Telecommunications and Information Technology, 2002
Accurate modeling of microwave monolithic integrated circuits (MMICs) is very desirable for the reason of high fabrication costs of GaAs circuits. Designers are trying to achieve the ``first trial success`` to lower costs and accelerate the introduction

Transmission Lines and Meta-Materials based on Quantum Hall Plasmonics

, 2018
The characteristic impedance of a microwave transmission line is typically constrained to a value $Z_0$ = 50 $ \Omega$, in-part because of the low impedance of free space and the limited range of permittivity and permeability realizable with conventional
