META 2024
14th International Conference on Metamaterials, Photonic Crystals and Plasmonics
Toyama, Japan, July 16 – 19, 2024
META 2024, the 14th edition of the International Conference on Metamaterials, Photonic Crystals and Plasmonics (Scopus-indexed proceedings), was held in Toyama, Japan, on 16–19 July 2024. This page is the archive of that edition: program, speakers, committees and proceedings. The previous edition in Paris had gathered 966 attendees from 43 countries over 148 technical sessions.
The program covered topics such as metasurfaces and metadevices, acoustic and phononic metamaterials, plasmon-enhanced spectroscopy, quantum and nonlinear photonics, and nanophotonics for biology and medicine.
The conference ran over four days, from Tuesday 16 to Friday 19 July 2024, with plenaries, keynotes, tutorials and special invited sessions on emerging and interdisciplinary topics.

Extreme Control of Light and Sound with Metamaterials
Andrea Alù, City University of New York (USA)
In this talk, I discuss recent developments in this field of research, with an emphasis on the role of symmetries in establishing emerging optical responses for metamaterials based on otherwise simple constituents. Geometrical rotations, suitably tailored perturbations, and broken time reversal symmetry can be carefully engaged to tailor waves in robust and efficient ways, control their propagation, break Lorentz reciprocity and enable topological order and phase transitions.
Structuring light with media with higher dimensions: space, time, and more
Nader Engheta, University of Pennsylvania (USA)
In this talk, I will present some of our most recent results on exploring light-matter interaction in material media with high degrees of freedom and dimensions including spatial and/or temporal inhomogeneities, and other degrees of freedom such as anisotropy, ellipticity, and hyperbolicity. We show how light manipulation with such metastructures with high degrees of freedom can lead to exciting novel wave phenomena with potential applications in wave-based reconfigurable analog computing, 4D optics, and other optical devices and components.
Active photonic metasurfaces empowered by 2D semiconductors
Isabelle Staude, Friedrich Schiller University Jena (Germany)
Experiments demonstrating extremely rapid modulation of the permittivity have been performed by exploiting the enhanced non-linear effects possible in the presence of plasmonic resonances. These experiments measure anextreme rise time by exploiting the analogy between Young’s slits which produce diffraction in momentum space and closely spaced time windows which produce diffraction in frequency space.
Extreme time modulation of material properties and Hawking radiation
Sir John Pendry, Imperial College London, (UK)
In this talk, I will present noticeable advances in the device technology for information and vision applications based on meta-photonics. The development in the field of integrated electronics devices has been incredibly fast, and this rapid development has been driven and accelerated by pioneering semiconductor manufacturing technologies that allow extreme scale-downs and creation of 3 dimensional structures. Meta-photonics can provide innovative platforms to produce unprecedented synergetic effect with electronics due to its distinguished capability of manipulating the control of light at the deep subwavelength scale. I will address how device technologies based on meta-photonics can contribute to making a better life, and share remarkable achievements and future goals we are working on.
Optical thermodynamics of highly multimode nonlinear photonic systems
Demetrios Christodoulides, University of Southern California, (USA)
In this talk, a thermodynamic theory capable of describing complex, highly multimoded, nonlinear optical systems is presented. It is shown that the mode occupancies in such nonlinear multimode arrangements follow a universal behavior that always tends to maximize the system’s entropy at steady-state. This thermodynamic response takes place irrespective of the type of nonlinearities involved and can be utilized to either heat or cool an optical multimode system. Aspects associated with adiabatic compressions and expansions will be discussed along with the possibility for all-optical Carnot cycles.
