AltaSim Uses Simulation to Improve Bolometer Sensitivity

Caty Fairclough | June 15, 2016

Bolometers have the ability to detect and measure the power of incident electromagnetic radiation. This allows them to be used in a range of technologies, from night vision cameras to far-reaching astronomy projects. Designing bolometers often requires devoting a lot of time and energy to the development phase, as these devices must be optimized for sensitivity and customized for their specific applications. To efficiently design bolometers with increased sensitivity, AltaSim Technologies utilized the simulation capabilities of COMSOL Multiphysics.

Ever been in a tall building on a windy day or had an aircraft pass over your house? Along with the noise that you hear, which can be disruptive and unpleasant in its own right, you’ll also notice some low-frequency vibrations that can ultimately affect the structure’s stability. One solution to this problem is to incorporate dampers, particularly viscoelastic structural dampers, into the structure’s design. With simulation apps, the path to optimizing these devices is more efficient than ever before.

When designing a device or process, it is important to not only study the system itself, but to also account for the effects of the environment around it. Historical weather data can help to address such effects by offering deeper insight into the weather patterns across different locations and time frames. Take a closer look at how such data can foster better design decisions, with a particular emphasis on its benefits within heat transfer modeling.

Reservoirs, dams, and other outdoor structures need to be strong, reliable, and sound. The porous materials found within these structures can be easily damaged by pressure changes that cause fluid flow and gradual caving and sinking. Using the multiphysics simulation capabilities of COMSOL Multiphysics and the Poroelasticity interface, we can accurately analyze porous materials to evaluate and avoid deformation in such structures.

When an electronic device overheats, it risks starting a fire. Cooling components, such as heat sinks, are designed to prevent this, but can’t always keep up with advancing technology. Simulation offers a solution by illustrating how well various heat sink designs conduct heat and how adding elements like manifold microchannels (MMC) improves performance. Today, we’ll explore how an MMC heat sink operates with simulation.
