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.<\/p>\n","protected":false},"featured_media":5596,"template":"","profile_category":[25],"class_list":["post-5091","profiles","type-profiles","status-publish","has-post-thumbnail","hentry","profile_category-2026-interns"],"acf":[],"_links":{"self":[{"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/profiles\/5091","targetHints":{"allow":["GET"]}}],"collection":[{"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/profiles"}],"about":[{"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/types\/profiles"}],"version-history":[{"count":4,"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/profiles\/5091\/revisions"}],"predecessor-version":[{"id":5991,"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/profiles\/5091\/revisions\/5991"}],"wp:featuredmedia":[{"embeddable":true,"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/media\/5596"}],"wp:attachment":[{"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/media?parent=5091"}],"wp:term":[{"taxonomy":"profile_category","embeddable":true,"href":"https:\/\/oge.mit.edu\/msrp\/wp-json\/wp\/v2\/profile_category?post=5091"}],"curies":[{"name":"wp","href":"https:\/\/api.w.org\/{rel}","templated":true}]}}
