Möbius Reparametrization of Multiport-Network Models of PIN-Diode-Programmable Metasurfaces for Accurate Low-Order Neumann Approximations
Philipp del Hougne
Accurate models of programmable metasurfaces based on multiport-network theory (MNT) account for mutual coupling (MC) through a configuration-dependent matrix inversion. The latter…
Wave-Domain Semantic Equalization Using a Practical Dynamic Metasurface Antenna with Strong Mutual Coupling
Yassine Sghaier, Emilio Calvanese Strinati, Philipp del Hougne
Semantic mismatch between independently trained AI-native agents in heterogeneous networks can impair semantic communications. Hybrid analog-digital semantic equalization can align…
RIS-Aided Wireless Multiport Sensing: Multiplexed De-Embedding of an RIS-Programmable Over-the-Air Fixture
Philipp del Hougne
Wireless multiport sensing aims to remotely retrieve the scattering matrix of a multiport device under test (DUT) connected to not-directly-accessible (NDA) antennas, based on scat…
Cross-Harmonic Ambiguity-Aligned Multiport Parameter Estimation for Time-Floquet RIS
Philipp del Hougne
A time-Floquet reconfigurable intelligent surface (TF-RIS) periodically modulates its elements within a signaling interval, enabling frequency conversion and additional degrees of…
Electromagnetic Bounds on Realizing Targeted MIMO Transfer Functions in Real-World Systems with Wave-Domain Programmability
Philipp del Hougne
A key question for most applications involving reconfigurable linear wave systems is how accurately a desired linear operator can be realized by configuring the system's tunable el…
Effective Electromagnetic Degrees of Freedom in Backscatter MIMO Systems
Philipp del Hougne
While the definition of the effective electromagnetic degrees of freedom (EEMDOFs) of a static linear multiple-input multiple-output (MIMO) system is well established, the counterp…
Physics-compliant diagonal representation of beyond-diagonal RIS
Philipp del Hougne
Physics-compliant models of RIS-parametrized channels assign a load-terminated port to each RIS element. For conventional diagonal RIS (D-RIS), each auxiliary port is terminated by…
Experimentally realized physical-model-based wave control in metasurface-programmable complex media
Jérôme Sol, Hugo Prod'homme, Luc Le Magoarou +1
The reconfigurability of radio environments with programmable metasurfaces is considered a key feature of next-generation wireless networks. Identifying suitable metasurface config…
Noise-Adaptive Intelligent Programmable Meta-Imager
Chenqi Qian, Philipp del Hougne
We present an intelligent programmable computational meta-imager that tailors its sequence of coherent scene illuminations not only to a specific information-extraction task (e.g.,…
