Simulation Of Optical Properties Of Dielectric Layers From Visible To Near Infrared Spectral Range, Andrew Cochran, Cory Conkel Apr 2021

Simulation Of Optical Properties Of Dielectric Layers From Visible To Near Infrared Spectral Range, Andrew Cochran, Cory Conkel

ONU Student Research Colloquium

Optical properties of dielectrics play a critical role in various applications including the design and manufacture of optical components & devices such as detectors, filters, imagers, lenses, optical coatings, photonic crystals, sensors and waveguides, and solar cells. Radiative properties of varying thicknesses of different dielectrics such as Aluminum Oxide (Al2O3), Silicon Dioxide (SiO2), Indium Tin Oxide (ITO), Magnesium Fluoride (MgF2) and Silicon Nitride (Si3N4) have been simulated and compared in the range of visible to near infrared by mathematical modelling using MATLAB simulations. The results of the evolution of the radiative properties, as a function of dielectric material thickness, on …


Hygrothermal Performance Of Sealed Attics In Climate Zone 3a, Mikael Salonvaara, Achilles Karagiozis, William Miller Sep 2018

Hygrothermal Performance Of Sealed Attics In Climate Zone 3a, Mikael Salonvaara, Achilles Karagiozis, William Miller

International Building Physics Conference 2018

Sealed attics with fiberglass have been in the US building codes for several codes cycles. Prior to the IRC 2018, air permeable insulation (such as fiberglass) was previously allowed to be deployed without continuous air impermeable insulation only in dry climate zones 2B and 3B in tile roofs systems. New research has revealed that asphalt shingles can also be allowed as implemented in the new IRC 2018 with a new addition to the section for sealed attics using air permeable insulations. The new building code also permits the use of air permeable insulation without air impermeable insulation in climate zones …


Classification Of The Indoor Environment In A High-School Building By Means Of Subjective Responses, Lorenza Pistore, Ilaria Pittana, Francesca Cappelletti, Andrea Gasparella, Piercarlo Romagnoni Sep 2018

Classification Of The Indoor Environment In A High-School Building By Means Of Subjective Responses, Lorenza Pistore, Ilaria Pittana, Francesca Cappelletti, Andrea Gasparella, Piercarlo Romagnoni

International Building Physics Conference 2018

In this paper the subjective evaluation of the indoor environment of a secondary school in Treviso (Italy) is presented. Field campaigns have been carried out during the winter season in order to assess people overall satisfaction about the environment, their behavior towards discomfort and their interactions with the building and the systems. A specific questionnaire has been elaborated, paying particular attention to the occupants target and to the questions needed to grasp not only the comfort feedbacks, but also the dynamics and the individual students’ attitudes that can influence the building energy performance. A first general evaluation has been elaborated …
