We present a three-dimensional finite-difference time-domain analysis of localized defect modes in an optically thin dielectric slab that is patterned with a two-dimensional array of air holes. The symmetry, quality factor, and radiation pattern of the defect modes and their dependence on the slab thickness are investigated. © 1999 Optical Society of America [S0740-3224(99)01302-8] OCIS codes: ...

orientation, i.e., with the beam direction, B , parallel to a principal zone. It was noted that the zone axis image quality, and hence defect contrast, are strongly dependent on the particular zone chosen. In this contribution, we propose that the defect image contrast quality from a given zone is directly related to the electron Kossel pattern (EKP), which is a function of crystal structure, o...

This case report describes the successful repair of an acquired ventricular septal defect following an anterior full thickness myocardial infarct in an 89 year old man. Four months after the infarct the patient was in severe congestive cardiac failure (NYHA Class IV), despite medical treatment, with signs of a ventricular septal defect. This was confirmed by echodoppler and cardiac catheterizat...

BACKGROUND Previous studies have shown that adequate thickness or initial augmentation of soft tissue has a positive effect on the stability of peri-implant bone. This randomized, controlled trial aimed to evaluate the influence of augmenting soft tissue with platelet-rich fibrin (PRF) on crestal bone and soft tissue around implants. METHODS After randomization, 31 fully threaded titanium imp...

A 5-year-old gelding used for showing was presented surgical repair of a full-thickness 15 mm diameter defect in the right pinna, which had occurred as delayed complication following laser excision sarcoid. The resulted progressive deformity ear, and horse considered at risk further injury if became entrapped on fixed object. Two artificial dermis meshes were inserted to encourage formation gra...

DESCRIPTION After sustaining a human bite to the right auricle, a 19-year-old man presented for management and reconstruction of a 2.6-cm isolated, full-thickness helical rim defect.

The paramedian forehead flap is a great option for restoration of complex nasal defects. For full-thickness defects, it may be used alone or in combination with other methods. We present a patient with a basal cell carcinoma on the distal nose treated by Mohs micrographic surgery, and a resulting full-thickness defect repaired with paramedian forehead flap combined with a hinge flap. For optima...

When a circularly polarized plane wave is normally incident on a slab of a structurally chiral material with local 4̄2m point group symmetry and a central twist defect, the slab can function as either a narrowband reflection hole filter for co–handed plane waves or an ultranarrowband transmission hole filter for cross–handed plane waves, depending on its thickness and the magnitude of the applie...
