An approximation technique is considered for computing transmission and reflection coefficients for plane waves propagating through stratified slabs. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is shown that it depends ...

The reflection and transmission of thermoelastic plane waves at an imperfect boundary of two dissimilar fibre-reinforced transversely isotropic thermoelastic solid half-spaces under hydrostatic initial stress has been investigated. The appropriate boundary conditions are applied at the interface to obtain the reflection and transmission coefficients of various reflected and transmitted waves wi...

This paper designs a miniaturized and ultrathin absorptive/transmissive radome based on interdigital square loops. The thickness of designed radome is only 4.5mm. The period of the radome is 10mm, which is λ/17.5 (λ corresponding to the wavelength of center frequency of passband). In order to verify the transmission and reflection properties, a prototype is fabricated. Its effectiveness is veri...

This paper presents a way to obtain angle-dependent reflection, transmission and absorption coefficients of sample based on the modal decomposition method in rectangular waveguide. Microphone locations are optimized ensure that can be applied. The is subsequently validated both numerically experimentally.

Waves in periodic media, whose propagation is governed by nearest neighbour interaction, are investigated. The reflection and transmission coefficients are derived for a plane wave incident from medium 1 upon medium 2, without invoking common approximations. The derivation is valid for a class of waves including magnetoand electro-inductive waves, waves on short loaded dipoles, nanoparticles, c...

An approximation technique is considered for computing transmission and reflection coefficients for propagation of an elastic pulse through a planar slab of finite width. The propagation of elastic pulse through a planar slab is derived from first principles using straightforward time-dependent method. The paper ends with calculations of enhancement factor for the elastic plane wave and it is s...
