摘要如果正好占满第一页，下一页空白页会显示页眉

当摘要写满第一页时，会导致第二页的空白页出现页眉，之前有个类似的issue我也看到了，但是他的问题是加了多余的空格，但是我检查了下我的没有加，而且我用的main.tex文件，没有用分立文件。

```latex \begin{englishabstract} Time-varying electromagnetic systems have emerged as a new focus of international research on metamaterials in recent years. Time-periodic electromagnetic structures, also known as temporal photonic crystals in optics, have attracted widespread attention due to their two key characteristics: temporal harmonics and wavevector bandgaps. In particular, there has been a growing interest in exploring the topological properties of temporal photonic crystals based on their similarity to traditional spatial photonic crystals. It has been theorized that topological boundary states exist in the time domain at the boundaries of temporal photonic crystals with different topological phases. However, due to challenges in physical construction, these concepts and properties are still largely theoretical and in the numerical analysis stage, lacking experimental verification. This thesis aims to construct equivalent temporal photonic crystals based on varactor-diode-based time-varying transmission lines in the microwave frequency range. It extracts the dispersion relations of the time-varying transmission lines and observes several characteristics of temporal photonic crystals, including time-domain topological boundary states. First, by analogy with the analysis methods of binary spatial photonic crystal systems, the solution of a sinusoidal time-varying temporal photonic crystal system is achieved using the transmission matrix method and the concept of spatial discretization. Subsequently, the microstrip transmission line circuit with periodically loaded varactor diodes is proposed as a platform for constructing equivalent temporal photonic crystals. A differential modulation architecture is introduced to greatly improve the isolation between the transmitted signal and the modulated signal in the circuit, ensuring the observability of the temporal evolution characteristics of the transmitted signal. Furthermore, through coordinated simulation using field-path equivalence and analysis of relevant simulation results, the effectiveness of the time-varying transmission line as a construct for temporal photonic crystals is confirmed. Finally, through sample processing and testing, several characteristics of temporal photonic crystals are verified, and preliminary observations of time-domain topological boundary states are confirmed. \englishkeyword{Time-varying Electromagnetic Structures, Temporal Photonic Crystals, Dispersion Relation, Topological Boundary State, Microstrip Transmission Line} \end{englishabstract} ```
