Programmable Microwave Communication Channel for Efficiency Harmonic Generation
Location
Hager-Lubbers Exhibition Hall
Description
PURPOSE: The manipulation of microwave signals has become increasingly important in the information industry. This research explores the application of time-coding techniques to engineer spoof surface plasmon polaritons (SSPPs) – the main carrier signal in this communication channel – for the programmable control of transmission through a communication channel. PROCEDURES: We focus on the simulation and analysis of the time-coding SSPPs in a communication channel with transmission properties that can be tuned using a microcontroller. Through the use of Ansys HFSS, a microwave simulation tool, we validate the "ON" and "OFF" modulation characteristics of the proposed SSPP structure by tuning the geometry of the waveguide in real time. OUTCOME: The presence of mounted PIN diodes facilitates the inherent tunability of the transmission of microwave signals. As a byproduct of the “ON” and “OFF” modulation characteristics, we are enabling efficient harmonic generation. These findings demonstrate the potential for establishing a direct connection between electromagnetic wave transmission behavior and time-domain digital coding, laying the groundwork for realizing programmable harmonic generation and amplitude manipulation. IMPACT: Future research, building upon the work of Zhang et al. (Appl. Phys. Lett. 121, 161702, 2022), will investigate various structures that promote SSPP propagation, aiming to suppress the fundamental component (DC component) and create customized asymmetric spectra. This work contributes to the development of intelligent communication and information systems by introducing time-coding technologies into microwave devices, facilitating the miniaturization and integration of programmable electromagnetic wave manipulation devices.
