| Zusammenfassung: | The non-reciprocal transmission metasurface based on time modulation sequentially comprises a first narrowband frequency selection surface, a time modulation transmission phase surface and a second narrowband frequency selection surface from top to bottom. The first narrowband frequency selection surface and the second narrowband frequency selection surface are formed by arranging a plurality of resonance unit structures, and the resonance units of the first narrowband frequency selection surface and the resonance units of the second narrowband frequency selection surface are similar in structure but different in size, so that electromagnetic waves of different frequencies can be transmitted; the time modulation phase surface is formed by arranging a plurality of phase adjustable units. The whole metasurface adopts a transmission mode, the time modulation transmission phase face can achieve frequency deviation by conducting time voltage modulation on continuous sawtooth waveforms, and non-reciprocal one-way t |
