Simplistic metasurface design approach for incident angle and polarization insensitive rcs reduction.

This paper proposes the design of a metasurface for polarization and incident angle-insensitive RCS reduction applications. An ellipse-shaped unit cell is utilized as a polarization converter, which is then arranged to form a checkerboard surface. While a single layer checkerboard structure gives a wideband RCS reduction, a double layer structure yields polarization and incident angle independent operation.

Assessment of Clinical Outcome of Root Coverage Following Coronally Advanced Flap with or without Amniotic Membrane.

Aim: The present study aimed to assess the clinical outcome of root coverage following coronally advanced flap with or without amniotic membrane in Miller's class I or class II localized gingival recession in relation to anteriors.

Methods: Five patients with bilaterally symmetrical Miller's class I or class II localized gingival recession were included in the study. Each patient was divided into control (without amniotic membrane) and test sites (with amniotic membrane) arbitrarily.

Randomized Controlled Study on Effect of Concentrated Growth Factors on Crestal Bone Levels and Peri-implant Bone Density in Dental Implants.

Introduction: Modern dentistry aims to restore the comfort and health of the stomatognathic system. Dental implants have emerged as a promising option for this purpose. Concentrated growth factors (CGFs) have been suggested to enhance the healing of bone grafts and enhance the integration of implants into the bone.
