在本论文中，我们介绍了通信渠道中链接预算估算的基本方程式，突出了传统系统的关键局限性。此外，我们研究了可重构智能表面作为克服障碍物损失的现代方法的使用，同时使用数值方法和计算电磁剂来了解其物理机制并探究其操作理论。此外，提出了计算几何形状的预印本，适用于计算电磁学领域，从而可以使用开源工具来模拟系统，例如可重构智能表面。最后，我们为基于数学编程的射频网络的物理优化提供了一种工具。这种工具可用于优化可重构的智能表面，最终改善发射器和接收器之间的通信通道。
In this thesis, we introduce the fundamental equations behind the estimation of the link budget in a communications channel, highlighting the key limitations of conventional systems. Furthermore, we investigate the use of reconfigurable intelligent surfaces as a modern method of overcoming obstruction losses, while making use of numerical methods and computational electromagnetics to understand its physical mechanism and probe its theory of operation. Additionally, a preprint on computational geometry is presented, applicable to the field of computational electromagnetics, enabling the simulation of systems such as reconfigurable intelligent surfaces using open-source tools. Lastly, we provide a tool for the physical optimization of radio-frequency networks, based on mathematical programming. Such a tool may be used for the optimization of reconfigurable intelligent surfaces, ultimately improving the communication channel between a transmitter and receiver.
