The ever-increasing performance and efficiency demands on new technologies, such as the upcoming 5G cellular standard and next-generation computing, will necessitate a transformative approach towards electronic hardware design all the way down to the electromagnetics level. Significant progress has been made towards the automation and optimization of circuits, especially digital logic circuits, via computer-aided design techniques. In fact, the advent of digital synthesis, or the automated design of digital circuits by computers, has brought hardware into reality which was previously thought impossible, such as microprocessors with billions of transistors occupying form-factors of a few square-cm and capable of performing billions of mathematical operations per second. Presently, the underlying circuit components of a system are designed separately from the electromagnetic (EM) blocks, often by different engineers or even different institutions altogether. Unfortunately, most EM devices such as antennas, microwave devices, and even nanophotonic devices in photonic integrated circuits must be painstakingly designed manually from the ground up by a human engineer. This process is not only tedious and time-consuming, but also suboptimal and often leaves significant performance gains on the table due to the enormous degrees of freedom available for designing such devices which are impossible for a human to explore. This project aims to tackle these issues by developing an automated synthesis platform for EM devices, analogous in spirit to digital logic synthesis, which will save human engineers significant time spent designing these devices manually and lead to novel, non-intuitive structures. This will be the first generalized synthesis platform which can handle a wide class of devices across the EM spectrum. This research will be complemented by an educational plan which includes the development of a new graduate class, training graduate and undergraduate students in multi-disciplinary fields, and motivating K-12 students to pursue careers in STEM.Analytical solutions for Maxwell's equations, which describe all EM devices, do not exist except for simple toy problems. This significantly complicates the design of new EM devices and requires heuristic approaches and many time-consuming manual parameter sweeps. Despite the potential for unprecedented performance and time savings, there does not presently exist an automated synthesis framework for general EM devices which can operate with modest computing power. This project will lead to the design of such an automated EM synthesis platform by developing a scripting language to describe arbitrary EM devices in both the optical and radio-frequency regimes, advancing high-speed EM simulation methods based on boundary integral equations to decrease compute time and memory required by several orders of magnitude, and leveraging automated optimization algorithms capable of realizing new devices with little to no human intervention. The long-term goal of the project is to enable even the nonexpert with only modest computing capability, such as a desktop workstation, to design many types of different electromagnetic devices rapidly and efficiently in a matter of minutes to hours.This award reflects NSF's statutory mission and has been deemed worthy of support through evaluation using the Foundation's intellectual merit and broader impacts review criteria.

对新技术的不断增长的性能和效率需求，例如即将到来的5G蜂窝标准和下一代计算，将需要对电子硬件设计进行变革性的方法，直到电磁层。通过计算机辅助设计技术，已经取得了重大进展，尤其是数字逻辑电路的自动化和优化。实际上，数字合成的出现或计算机对数字电路的自动设计使硬件变成了现实，例如以前认为这是不可能的，例如，具有数十亿个晶体管的微处理器占据了数十亿个平方CM的形式因子，并且能够每秒进行数十亿个数学操作。目前，系统的基础电路组件是与电磁（EM）块分开设计的，通常是由不同的工程师甚至不同机构完全设计的。不幸的是，大多数EM设备（例如天线，微波设备，甚至是光子综合电路中的纳米光设备）都必须由人类工程师从头手动设计。这个过程不仅是乏味且耗时的，而且次优，而且由于可用于设计这种设备的巨大自由度，因此在桌面上经常在桌子上留下显着的性能增长。该项目旨在通过为EM设备开发自动合成平台来解决这些问题，该平台在精神上类似于数字逻辑综合，这将节省人工工程师在手动设计这些设备并导致新颖，非直觉结构的大量时间。这将是第一个可以在EM频谱上处理一类设备的广义合成平台。这项研究将得到一项教育计划的补充，该计划包括开发新的研究生班，培训毕业生和多学科领域的本科生，并激励K-12学生在STEM中从事职业。这显着使新EM设备的设计变得复杂，并且需要启发式方法和许多耗时的手动参数扫描。尽管有可能进行前所未有的性能和时间节省，但目前尚未存在可以使用适度计算能力运行的一般EM设备的自动合成框架。 This project will lead to the design of such an automated EM synthesis platform by developing a scripting language to describe arbitrary EM devices in both the optical and radio-frequency regimes, advancing high-speed EM simulation methods based on boundary integral equations to decrease compute time and memory required by several orders of magnitude, and leveraging automated optimization algorithms capable of realizing new devices with little to no human intervention.该项目的长期目标是仅具有适度的计算能力（例如桌面工作站），即使在数分钟到几个小时内迅速，有效地设计了许多类型的不同电磁设备。这奖反映了NSF的法定任务，并通过使用基金会的智力效果评估了支持。
