The optical dispersive prism is a well-studied element, which allows separating white light into its constituent spectral colors, and stands in nature as water droplets. In analogy to this definition, the acoustic dispersive prism should be an acoustic dev ...
We discuss our recent investigations on breaking time-reversal and spatio-temporal symmetries to provide novel functionalities in the field of metamaterials, with special emphasis on the field of acoustics and sound manipulation. ...
The intensity of a nonlinear terahertz (THz) source is primarily given by its spectral density. In this letter, we introduce triangular Selinium (Se) as a novel THz emitter and show numerically its superior properties to the currently used crystals for int ...
We prove that balanced loss-gain distributions provide an elegant path towards realizing loss-free unidirectional cloaks for objects much larger than the wavelength. By coating a scatterer with an ultrathin metasurface with balanced loss and gain, such as ...
Plasmonics has emerged as an important research field in nanoscience and nanotechnology. Recently, significant attention has been devoted to the observation and the understanding of nonlinear optical processes in plasmonic nanostructures, giving rise to th ...
The development of metamaterials, i.e., artificially structured materials that interact with waves in unconventional ways, has revolutionized our ability to manipulate the propagation of electromagnetic waves and their interaction with matter. One of the m ...
Sensing an incoming signal is typically associated with absorbing a portion of its energy, inherently perturbing the measurement and creating reflections and shadows. Here, in contrast, we demonstrate a non-invasive, shadow-free, invisible sensor for airbo ...
The present invention concerns a magnetic-photoconductive material including orientable magnetic moments or spins, the material being configured to generate photo-carriers permitting to orientate or re-orientate the magnetic moments or spins at a material ...
Measurement of thermal radiation through uncooled bolometers is at the heart of many industrial applications. From the development of the Honey- well silicon microstructure developed in 1982, no particular change in paradigm was recorded. The advent of 2D- ...
Novel electroresponsive silicone elastomers modified with nitrile groups are presented, whose dielectric permittivity (epsilon') is tuned from epsilon' = 4.3 to epsilon' = 17.4. They are prepared in a one-step process starting from a high molecular weight ...
