In spite of a growing body of research and data, human ageing remains a poorly understood
process. Over 10 years ago we developed the Human Ageing Genomic Resources (HAGR)…

… The sub-wavelength focusing is achieved as far as the parameter F/D remains below 0.25,
where F is the focal length and D the length of the metasurface [24]. An experimental …

… of 200 layers, where each layer of thickness d is composed of two alternate layers of thickness
of materials 1 and 2, respectively, ie d = d1 +d2 = d/2+d/2. The cloaking effect is evident in …

It has been shown that two-dimensional arrays of rigid or fluidlike cylinders in a fluid or a gas
define, in the limit of large wavelengths, a class of acoustic metamaterials whose effective …

… The lens thickness d ⁠, which is the factor leading the discrepancy between the ray method
and measurement/simulation results, is obtained from d = N ( 3 / 2 ) a + k ⁠, where N is the …

We show that specially designed two-dimensional arrangements of full elastic cylinders
embedded in a nonviscous fluid or gas define (in the homogenization limit) a new class of …

We present the design, construction, and experimental characterization of the acoustic
analogue of the so called photonic black-hole. The fabricated sample has cylindrical symmetry …
