SSPP leaky-wave radiation based on sinusoidal imped ance modulation

International Conference on Microwave and Millimeter Wave Technology, 2022
Due to the high gain, low profile, and high directionality of the leaky-wave antenna (LWA), the leaky-wave antenna has received a lot of attention since it was proposed. In this paper, a leaky-wave antenna with an asymmetric S-shaped structure based on a

Double-Modulation-Wave PWM-Based Power Flow Control of Single-Stage Dual-Port Inverters for Hybrid Electric Vehicles

IEEE Transactions on Transportation Electrification
The single-stage dual-port inverter (SSDPI) emerges as a high-efficiency power-electronic interface for hybrid electric vehicles (HEVs) due to the removal of dc-dc converters and the reduction of the power conversion stage. However, the modulation design

Role of cross-phase modulation with the pump wave for the narrow generation regime of a random fiber laser

SPIE/COS Photonics Asia
In present paper we discuss the role of interaction between the pump and generation waves in a fiber laser with randomly distributed feedback due to weak Rayleigh backscattering, operating in the ultra-narrow regime, observed just above the generation ...

Instability modulation for the (2+1)-dimension paraxial wave equation and its new optical soliton solutions in Kerr media

Physica Scripta, 2020
In this paper, we use the modified auxiliary expansion method to seek some new solutions of the paraxial nonlinear Schrödinger equation. The solutions have a hyperbolic function, trigonometric function, exponential function, and rational function forms ...

Collaborative Control Method of Midpoint Voltage and Zero Sequence Current in Inverter System Based on Modulation Wave Decomposition or Offset

2025 Zhejiang Power Electronics Conference (ZPEC)
The neutral point (NP) potential balance of multiple groups of independent DC buses in back-to-back parallel converter system conflicts with the control of zero- sequence circulating current (ZSCC) suppression in the system, because they are realized by ...
