                                With the rapid development of electric vehicles, power electronics, aerospace systems, satellite communications, and high-frequency semiconductor devices, electronic components are increasingly required to operate under high power, high temperature, and high frequency conditions. In such demanding environments, traditional organic or metal-based substrates often fail to provide sufficient thermal and electrical stability.
