Today’s exploding demand for faster, more reliable, and ubiquitous radio systems in communications, instrumentation, radar, imaging and sensors poses unprecedented challenges in microwave (mw), millimeter-wave (mmw) and terahertz (THz) engineering. Recently, the predominant trend has been to place increasing emphasis on digital signal processing (DSP). However, while offering device compactness and processing flexibility, DSP suffers from intrinsic drawbacks, such as limited speed, high-cost analog-digital conversion, high power consumption, and poor performance at high frequencies, leading to serious technological bottlenecks. For instance, in wireless communications, a 1,000-fold increase in data capacity demand over the 5 next years has been predicted, and it is widely recognized by industrial experts that current technologies will be largely insufficient to meet such requirements! Therefore, novel paradigms and disruptive technological solutions are urgently needed.

当今通信、仪器仪表、雷达、成像和传感器对更快、更可靠和无处不在的无线电系统的需求呈爆炸式增长，这对微波（mw）、毫米波（mmw）和太赫兹（THz）工程提出了前所未有的挑战。近年来，数字信号处理（DSP）的发展趋势越来越突出。然而，DSP在提供器件紧凑性和处理灵活性的同时，也存在固有的缺陷，如速度有限、模数转换成本高、功耗高、高频性能差等，导致了严重的技术瓶颈。例如，在无线通信中，已经预测在未来5年内数据容量需求将增长1,000倍，并且工业专家广泛认识到，当前技术将在很大程度上不足以满足这样的需求！因此，迫切需要新的范式和颠覆性的技术解决方案。
