As the demand for increasingly powerful computing systems continues to grow, overcoming
the speed limitations of conventional semiconductor electronics has become a major research
challenge. For decades, modern computer architectures have relied on semiconductor transistors
as their fundamental switching elements. While advances in semiconductor manufacturing
have dramatically improved transistor performance, conventional electronic devices remain
fundamentally limited to gigahertz-scale switching frequencies. As an alternative, the emerging
field of Petahertz electronics has demonstrated on-chip nanoscale devices capable of generating
photocurrents driven by optical fields at frequencies up to 5 orders of magnitude higher than
conventional electronics. However, to fully realize scalable optical-frequency electronic circuits,
researchers require accurate and accessible electrical models that enable efficient simulation and
analysis of these nanoscale devices. This project focuses on updating existing circuit models of
nanoantenna devices implemented in Ltspice and developing more compact, modular circuit
models that encapsulate their underlying behavior while simplifying their integration into
larger circuit architectures. In addition, this work develops a streamlined simulation and postprocessing
framework to automate simulation and analysis. By making nanoantenna models
more accessible and easier to use, this project aims to accelerate research of the design and
simulation of optical-frequency electronic circuits for future petahertz computing technologies.
