PhD in Dynamic Space–Time Interfaces for High-Speed THz Beam Control Eindhoven University of Technology in Netherlands

This PhD project at Eindhoven University of Technology (TU/e) explores dynamic space–time interfaces for high-speed THz beam control. The work sits at the intersection of photonics, electromagnetics, structured waves, nanofabrication, and experimental terahertz systems, with a strong focus on the emerging sub-THz regime (approximately 0.3–1 THz).

You will investigate what becomes possible when a THz interface changes while the wave is interacting with it. The project aims to develop dynamically modulated interfaces that can enable frequency conversion, beam steering, anomalous scattering, and nonreciprocal propagation. A major goal is to demonstrate GHz-rate two-dimensional spatiotemporal beamforming for future reconfigurable and nonreciprocal THz communication.

Your research will cover the full pipeline from concept development and electromagnetic modelling to device fabrication and THz experiments. Specific activities include designing fast spatial and temporal modulation schemes, modelling wave interactions with time-varying interfaces, exploring MEMS-based and alternative dynamic platforms, fabricating and characterizing devices, and building experiments to measure beam steering, frequency shifts, and nonreciprocal response.

The position is part of SPARK – Spatiotemporal Photonic Technologies, a Marie Skłodowska-Curie Actions Doctoral Network funded by the European Union under Horizon Europe. You will be based at TU/e in the Photonics and Semiconductor Nanophysics (PSN) group, and will also spend time at the Université de Namur for theoretical modelling and at TNO for THz mode (de)multiplexing and system-level characterization. The role includes participation in network-wide training schools, workshops, conferences, and collaborative activities.

Applicants should hold a relevant master’s degree and have a strong foundation in electromagnetics, wave physics, microwave/THz engineering, and/or photonics. Experience with numerical modelling or scientific programming is beneficial, as is interest in dynamic electromagnetic systems, metasurfaces, MEMS, RF/microwave systems, and experimental wave characterization. Strong English communication skills are required. The project values curiosity, a solid technical background, and willingness to learn new methods during the PhD.

Employment is for four years full-time, with an intermediate assessment after nine months. The salary follows Dutch university scale P and includes holiday allowance, year-end bonus, pension benefits, leave provisions, training opportunities, and support for international staff. Applications are reviewed on a rolling basis, with a deadline of 2026-11-10.
