Asymmetric frequency conversion with acoustic non-Hermitian space-time varying metamaterial
Xinhua Wen, Xinghong Zhu, Alvin Fan +5
Space-time modulated metamaterials support extraordinary rich applications, such as parametric amplification, frequency conversion and non-reciprocal transmission. However, experim…
Reconfigurable Intelligent Surfaces and Metamaterials: The Potential of Wave Propagation Control for 6G Wireless Communications
George C. Alexandropoulos, Geoffroy Lerosey, Merouane Debbah +1
The future 6G of wireless communication networks will have to meet multiple requirements in increasingly demanding levels, either individually or in combinations in small groups. T…
Curved-field optical coherence tomography: large-field imaging of human corneal cells and nerves
Viacheslav Mazlin, Kristina Irsch, Michel Paques +2
High-resolution optical imaging methods, such as confocal microscopy and full-field optical coherence tomography, capture flat optical sections of the sample. If the sample is curv…
Real-time, non-contact, cellular imaging and angiography of human cornea and limbus with common-path Full-field/SDOCT
Viacheslav Mazlin, Peng Xiao, Jules Scholler +4
In today's clinics, a cellular-resolution view of the cornea can be achieved only with an in vivo confocal microscope (IVCM) in contact with the eye. Here, we present a common-path…
Curved-Full-Field OCT for high-resolution imaging of living human retina over a large field-of-view
Pedro Mecê, Kassandra Groux, Jules Scholler +4
Allying high-resolution with a large field-of-view (FOV) is of great importance in the fields of biology and medicine, but particularly challenging when imaging non-flat living sam…
