Monolithic Integration of ScAlN Modulators on Silicon‐On‐Insulator Platform
Laser &Photonics Reviews, EarlyView.Monolithic integration of scandium‐doped aluminum nitride (ScAlN) modulators on a silicon‐on‐insulator platform is reported. A multilayer electrode design enhances RF‐optical field overlap, enabling direct access to the diagonal electro‐optic coefficient and improved modulation efficiency.

Incremental Forming of Sandwich Panels
Journal of Materials Processing Technology, 2007This paper presents a first investigation of the applicability of incremental sheet forming (ISF) to sandwich panels. Two initial tests on various sandwich panel designs established that sandwich panels which are ductile and incompressible are the most suitable for the process.

Eccentrically loaded sandwich panels
International Journal for Numerical Methods in Engineering, 1977AbstractThe paper deals with the design of eccentrically loaded sandwich panels in civil engineering structures. A theoretical analysis taking into account the non‐linear stress–strain properties of the materials and the influence of shear deformations is proposed. A computer program based on the described algorithm is used to solve a numerical example.

This chapter will briefly go over some of the types of damage that honeycomb sandwich panels suffer and the principles of repair. Military Handbook 337 (1982) Adhesive Bonded Aerospace Structural Repair is an excellent source for detailed repair procedures. It replaces and updates the old Military Handbook 23 (1968) repair section.
