PhD position on Nonlinear Topological Metamaterials

This PhD position at ETH Zürich focuses on the development of nonlinear topological metamaterials, with the aim of advancing methods for nonlinear wave manipulation and topologically-protected waveguides. The research will primarily involve acoustic metamaterials, leveraging the mutual and external synchronization of tunable self-oscillating meta-atoms to enable energy gain from the metamaterial itself, overcoming dissipation losses typical of conventional designs. The project encompasses engineering metamaterials that provide nonlinear topological protection for information transmission, deriving theoretical models, and experimentally demonstrating their unique properties. Practical implementations will utilize 3D-printed whistles exhibiting special scattering phenomena such as nonlinear cloaking and non-reciprocal amplified transmission, interconnected in periodic networks. There are plans to extend findings to microwave systems, broadening the impact of the research. The successful candidate will join a top-level research environment with advanced laboratory infrastructure, contributing to publications in leading journals. ETH Zürich offers a supportive and inclusive culture, with benefits including public transport tickets, sports facilities, childcare, and attractive pension schemes. The university values diversity, sustainability, and equality of opportunity, fostering a climate-neutral future. Applicants should have a strong MSc background in Mechanical Engineering, Electrical Engineering, or Physics, with excellent theoretical modeling skills and a passion for wave phenomena. The position is ideal for motivated, creative, and communicative individuals eager to work in a collaborative setting. Applications must be submitted online, including a motivation letter, CV, references, and transcripts. The deadline for applications is November 24, 2025.
