Using a square lattice design with square-shaped EFCs, we enable the group velocity vector to always be perpendicular to the lens interface irrespective of the frequency and incidence angle thus, resulting in a broadband imaging capability. In this work, we propose a PC lens for broadband subwavelength imaging of flexural waves in plates exploiting the second phonon band and the anisotropy of a PC lattice for the first time.

Whereas, for the left-handed materials, the subwavelength imaging is restricted to a narrow frequency region where wave vectors in PC and background material are close to each other, which is essential for single-point image formation. In the first phonon band, the imaging phenomenon can only exist at frequencies closer to the first Bragg band gap where the equal frequency contours (EFCs) are convex. 35 public primary schools extend the Bilingual Programme to the second pre-school cycle.Subwavelength imaging of elastic/acoustic waves using phononic crystals (PCs) is limited to a narrow frequency range via the two existing mechanisms that utilize either the intense Bragg scattering in the first phonon band or negative effective properties (left-handed material) in the second (or higher) phonon band.Almost 60% of secondary schools participate in the Global Classroom Model United Nations Programme.97,5% of the students sitting for the Bachibac exam pass it successfully.Nearly 200 schools and more than 1.200 teachers have participated in the MentorActúa programme.The Training Plan in Foreign Languages created 2.340 job positions during the 2016-2017 period.The Bilingual Program has already been implemented in the 51% of the Secondary Education Institutes and in the 46,6% of the public schools of the Community of Madrid.More than 2.000 secondary school teachers and over 3.600 primary school teachers have a competence level C1 in the English language.82% of sixth-grade students reach the target level specified in the external evaluations given in bilingual public schools.2.407 conversation assistants contribute a great multicultural and linguistic variety in Madrid’s schools.
