Sora, Bianca (author)This paper analyses the use of natural light as a design element in museums. While the design of natural light is important for all types of buildings, it takes additional layers of complexity in museum buildings and exhibition spaces. Due to the need to preserve the artwork, museums tend to become black boxes, with no interaction with the...student report 2024

William Kosta, Kosta (author)Architecture is a blend between art and science. It is a science and very rational in the way that the design solution has to work logically, structurally and rationally in terms of the organisation of space in relation to its function. There are many different design solutions to an architectural brief and the creative nature of working on the...student report 2024

Dou, X. (author)In the semiconductor industry, the minimumelement size has stepped into nanometer level. To keep the functionality of fabricated nanostructures, there is a huge demand of a technique that can provide non-destructive inspection and allow for in-line or in-situ monitoring during the manufacturing process. Optical scatterometry, which uses the far...doctoral thesis 2024

Liu, Minne (author), Li, Wenyu (author), Chen, Wei (author), Ibrahim, Mesfin S. (author), Xiong, Jingkang (author), Zhang, Kouchi (author), Fan, Jiajie (author)During the operation of an LED array, its thermal and optical performances are always not equal to the superposition of the individual LED's characteristics because of a significant thermal coupling effect between the arrays. Based on this, this paper proposes an electrical–photo-thermal model, with considering both junction temperature and...journal article 2024

Konijnenberg, A.P. (author), Adam, A.J.L. (author), Urbach, Paul (author)This book treats optics at the level of students in the later stage of their bachelor or the beginning of their master. It is assumed that the student is familiar with Maxwell’s equations. Although the book takes account of the fact that optics is part of electromagnetism, special emphasis is put on the usefulness of approximate models of optics...book 2024

Dupont, Samuel (author), Kastelik, Jean-Claude (author), Vanhamel, J. (author), Dekemper, Emmanuel (author)Diffraction of optical waves by an acoustic grating is a well-known phenomenon that enables the design of very versatile devices useful in photonic systems. For example, Acousto-Optic Tuneable Filters (AOTFs) can be dynamically tuned by radio-frequency signals. Among possible material choice, tellurium dioxide crystal is often used for practical...conference paper 2024
