Transfer matrix analysis of the elastostatics of one-dimensional repetitive structures [PDF]

, 2006
Transfer matrices are used widely for the dynamic analysis of engineering structures, increasingly so for static analysis, and are particularly useful in the treatment of repetitive structures for which, in general, the behaviour of a complete structure ...

Simultaneous Existence of Phononic and Photonic Band Gaps in Phoxonic Crystal Slabs [PDF]

, 2010
We discuss the simultaneous existence of phononic and photonic band gaps in a periodic array of holes drilled in a Si membrane. We investigate in detail both the centered square lattice and the boron nitride (BN) lattice with two atoms per unit cell ...

Tunable periodic microstrip structure on GaAs wafer [PDF]

, 2009
A one dimensional tunable periodic structure in microstip technology on gallium arsenide (GaAs) substrate is numerically investigated. The unit cell contains a number of patches positioned between the ground plane and the microstrip line.

Revealing defects in periodic structures

Міжнародний науково-технічний журнал "Проблеми керування та інформатики"
Rejection of defective parts and elements is an important part in quality improvement, maintenance and accident prevention. Some imaging instrumental methods of test and inspection have improved ability to reveal defects, but currently have ...

Radiative Transport in a Periodic Structure [PDF]

Journal of Statistical Physics, 1999
We derive radiative transport equations for solutions of a Schrödinger equation in a periodic structure with small random inhomogeneities. We use systematically the Wigner transform and the Bloch wave expansion. The streaming part of the radiative transport equations is determined entirely by the Bloch spectrum, while the scattering part by the random ...

Explicit error bounds for the α-quasi-periodic Helmholtz problem

, 2013
This paper considers a finite element approach to modeling electromagnetic waves in a periodic diffraction grating. In particular, an a priori error estimate associated with the α-quasi-periodic transformation is derived.
