摘要：
We introduce a perfect-frequency-converter meta-surface based on the effects of inharmonic photonic transition in twin time-modulated radiating patches. The medium is characterized with a periodic temporal modulation and a tailored aperiodic spatial profile. Such an aperiodic spatial profile provides aperiodic photonic bandgaps which prevent photonic transitions to unwanted time harmonics. Full-wave simulation results demonstrate a pure frequency conversion. The unique property of the proposed platform is the large frequency difference between the incident and transmitted waves. Therefore, this makes it suitable for modern wireless telecommunication systems.
