Design of a circular Dammann grating
Optics Letters, 2006A novel circular Dammann grating is proposed to generate uniform-intensity impulse rings corresponding to different diffraction orders in the far field. The intensities of the rings are determined by the coefficients of the circular sine series decomposition of the grating function. The definition of diffraction efficiency and uniformity for this novel

Minimum weight design of circular plates
Journal of the Mechanics and Physics of Solids, 1956Abstract The theory of minimum weight design of circular thin plates and circular sandwich plates obeying v. Mises's yield condition is discussed. It is shown that the minimum weight design admits a failure mechanism for which the mechanical energy dissipated per unit volume has a constant value throughout the plates.

Circular product design challenges: An exploratory study on critical barriers
Business Strategy and the EnvironmentDespite the recognition that the adoption of the circular economy depends on aligning the new product development process with the principles of circularity, there are still few studies on the barriers to circular product design.
