“…32 Some studies pointed out that the thickness ratio had a significant influence on the flexural strength of the bilayered systems. [4][5][6][7][8][9][10][11][12][13][14] That may be related to a different test method, the nature of the interface, and the properties of the materials, especially Young's modulus and flexural strength of each material. 4,5,7,8,13 Table 2 shows that the failure loads measured are close to the predicted values, confirming the validity of the failure load prediction model (Fig 4).…”

“…4,14 Hsueh et al 13 pointed out that the location of the maximum tensile stress of bilayered discs in a biaxial bending test changed with the thickness ratio, thus, the strength and failure mode can be affected; however, some studies found that strength was not dependent on the thickness ratio. 6,7,10 The different conclusions indicate that the effect of thickness ratio has not been clearly revealed. Hence, investigating the stress distribution in the beams is paramount to understanding the effect of the thickness ratio on their strength and failure mode.…”

“…Consequently, considerable research has been conducted on the strength and failure mode of the all-ceramic bilayered systems, including disks and beams, which have similar stress patterns to the FPD connector. [3][4][5][6][7][8][9][10] Thickness ratio can affect failure mode and failure origin for both bilayered disk and beam specimens. 4,[9][10][11][12][13] Some investigations have shown that strength increased as the core/veneer thickness increased.…”

The residual thermal stresses in the core layer have slightly beneficial effects on the strength of the beams. The first strength theory can be used to explain the mechanism of failure, which can be described as the failure is interpreted by tensile stress and ultimate strength of the material. Based on the relationship between the thickness ratio and load-bearing capacity, the core/veneer thickness ratio of the connector of a fixed partial denture could be relatively small to about 1:2 to obtain a good appearance.

“…Titanium is used due to its adhesion properties to metal and silicon. Also, following layer deposition, layer peeling, de-lamination, or separation due to thermal stress was a risk due to the different thermal expansion coefficients of Cu, Si, and SiO 2 [72] and the rapid cooling from 350 C to room temperature post-fabrication, but this phenomena was not observed in this experiment.…”

“…To obtain a narrow absorption band around the desired resonant frequency, the number of alternating layers can be increased. Although this is conceptually a simple technique to achieve high Q-factors, typically > 100, the fabrication process can be challenging as thickness and stress of each layer must be accurately controlled for a large number of layers [72].…”

A thermal emitter using a metasurface to tailor the emission spectrum in the mid-infrared for gassensing applications is demonstrated. The design consists of an array of high index dielectric elliptical pucks above a metal back-reflector. Using full-wave simulations in HFSS (Ver. 19.0.0), it has been shown that the achievable Q-factor (Q ≈ 150) in this structure is an order of magnitude larger than in plasmonic arrays (Q ≈ 16), attributed to the low-loss in the dielectric materials. Furthermore, the thermal emission properties of the structure can be engineered by manipulating Accomplishment of my thesis would not have been possible without the support of a few special people. I would like to acknowledge and thank my thesis supervisors Dr. Niall Tait and Dr. Shulabh Gupta from the bottom of my heart for providing consistent support and encouragement to complete this task. Specially going through and fixing the multiple drafts of my thesis and help with the journal papers. This project involved a lot of nanofabrication which is time consuming and requires a lot of expertise in terms of equipment usage and experience. I would like to extend my sincere thanks to Robert Vandusen, Angela M. Williams and Rodney Aiton for their continuous support during fabrication failures and encouragement and appreciation on my successes. I would like to specially thank Nagui Mikhail for helping me specially when it came to simulation and technical support related to my project. Thanks to the Department of Electronics Engineering, particularly Nagui Mikhail, Blazenka Power, Anna Lee and Valerie Daley for their help. I would like to extend gratitude to my close friend Muhammad Asif for being my continuous support during this project. His words of encouragement and advises throughout my stay in Ottawa helped me navigate the highs and lows of my academic journey. I would also like to thank my dear friend Raheel Ahmed for his help and support towards the completion of my project. I would specifically like to acknowledge his mastery on graphical designing software that helped me in translating my fabricated devices into figures. My deepest thanks goes to my family for being my continuous support in this journey. My Wife, Naureen Aqueel was always there to help me specially raising our two sons Muhammad Abdurrahman Ali and Muhammad Yasir Ali while I was working late hours at Carleton University working on my projects and writing my thesis. She was my constant support and encouragement and believed in me for successful completion of my project.
