A Design Technique Based on Equivalent Circuit and Coupler Theory for Broadband Linear to Circular Polarization Converters in Reflection or Transmission Mode [PDF]
IEEE Transactions on Antennas and Propagation, 2018 A new approach to designing frequency selective surface (FSS)-based linear to circular polarization (LP–CP) converters is presented. It is based on the use of FSSs which exhibit dual diagonal symmetry, and a novel four-port equivalent circuit able to ...

A New Doherty Combiner with Wide Bandwidth for Magnitude and Phase Balance Compensation [PDF]
Journal of Electromagnetic Engineering and Science, 2023 This paper proposes a novel Doherty combiner that uses a series and parallel resonant circuit for wideband. Unlike conventional combiners, the aim of the proposed combiners is to extend bandwidth for not only the magnitude bandwidth, but also phase ...

Investigation on four‐port mono‐capacitor circuit with high‐pass negative group delay behavior
International journal of circuit theory and applications, 2021 Most of the recent studies on unfamiliar negative group delay (NGD) circuit were focused on the classes of low‐pass (LP) and bandpass (BP) topologies. So far, few research works are currently available in the literature on the high‐pass (HP) NGD class ...

IEEE Transactions on Quantum Engineering, 2021 Classical microwave circuit theory is incapable of representing some phenomena at the quantum level. To include quantum statistical effects, various theoretical treatments can be employed. Quantum input-output network (QION) theory is one such treatment.

Characterizing Inductive and Capacitive Nonlinear RLC Circuits: A Passivity Test [PDF]
, 2004 Linear time-invariant RLC circuits are said to be inductive (capacitive) if the current waveform in sinusoidal steady-state has a negative (resp., positive) phase shift with respect to the voltage.
