Surface Wave Effects on the Reflection Phase of Curved High Impedance Surfaces
Durgun, Ahmet Cemal; Birtcher, Craig R. (2013-01-01)
For most cases, the reflection phase diagram of a curved High Impedance Surface (HIS) is independent of the curvature. However, the surface waves generated on HISs, due to their periodic geometry, distorts their reflection characteristics within specific frequency intervals. In those intervals, the reflection phase changes as a function of radius of curvature and size of the HIS. These effects are not observed for the flat cases because of the lower radiation resistance of the surface waves.
Surface response of a viscoelastic medium to subsurface acoustic sources with application to medical diagnosis
Royston, Thomas J.; Yazıcıoğlu, Yiğit; Loth, Francis (Acoustical Society of America (ASA), 2003-02-01)
The response at the surface of an isotropic viscoelastic medium to buried fundamental acoustic sources is, studied theoretically, computationally and experimentally. Finite and infinitesimal monopole and. dipole sources within the low audible frequency range (40-400 Hz) are considered. Analytical and numerical integral solutions that account for compression, shear and surface wave response to the, buried sources are formulated and compared with numerical finite element simulations and, experimental studies ...
Surface Wave Suppression Properties of Perforated Artificial Impedance Surfaces
Durgun, Ahmet Cemal; Birtcher, Craig R. (2013-01-01)
Surface wave suppression properties of Perforated Artificial Impedance Surfaces (PAIS) are investigated. It is shown that, by a proper choice of perforation geometry, surface wave propagation can be suppressed without the need of vias. This significantly decreases fabrication costs. It is also possible to overlap the surface wave suppression and reflection phase bands of the PAIS. Due to the rotational asymmetry of the structure, surface wave suppression is achieved in only one direction.
