Heikkola, E. (author), Mönkölä, S. (author), Pennanen, A. (author), Rossi, T. (author)We consider the use of controllability techniques to solve the Helmholtz equation. Instead of solving directly the time-harmonic equation, we return to the corresponding time-dependent equation and look for time-periodic solution. The convergence is accelerated with a control technique by representing the original time-harmonic equation as an...conference paper 2006

Rossi, M. (author), Lindken, R. (author), Westerweel, J. (author)Multiplane ?PIV can be utilized to determine the wall shear stress and wall topology from the measured flow over a structured surface. A theoretical model was developed to predict the measurement error for the surface topography and shear stress, based on a theoretical analysis of the precision in PIV measurements. The main parameters that...journal article 2009

(author)This paper presents a microhotplate working up to 1200 °C with improved temperature uniformity by optimizing the geometry of the thin-film resistor. By varying the linewidth of meandering resistive tracks, heat is generated in such a way to have more homogenous temperature distribution. The microhotplates are fabricated using molybdenum as...journal article 2011

Rossi, M. (author), Marin, A. (author), Wang, C. (author), Hilgenfeldt, S. (author), Kähler, C.J. (author)Ultrasound-driven gas bubbles can be used as active actuators to create or modify the flow in microfluidic devices. Oscillating bubbles are able to create a steady streaming flow that can be used to perform several tasks in microfluidic devices. In this work, we focus on a specific configuration with a bubble located at a side wall of a...conference paper 2013

(author)Magnetic force microscopy (MFM) is an atomic force microscopy (AFM) based technique in which an AFM tip with a magnetic coating is used to probe local magnetic fields with the typical AFM spatial resolution, thus allowing one to acquire images reflecting the local magnetic properties of the samples at the nanoscale. Being a well established tool...journal article 2014

Berzosa Molina, Javier (author), Stam, D.M. (author), Rossi, L.C.G. (author)The detection of moons around extrasolar planets is one of the main focuses of current and future observatories. These silent companions contribute to the planets' observed signals but are barely detectable with current methods. Numerous gaseous exoplanets are known to orbit in the habitable zones of stars, and the expected abundance of natural...abstract 2017

Rossi, L.C.G. (author), Stam, D.M. (author)Context. Clouds have already been detected in exoplanetary atmospheres. They play crucial roles in a planet’s atmosphere and climate and can also create ambiguities in the determination of atmospheric parameters such as trace gas mixing ratios. Knowledge of cloud properties is required when assessing the habitability of a planet.<br/><br/>Aims....journal article 2017

Rossi, L.C.G. (author), Stam, D.M. (author)The circular polarization of light that planets reflect is often neglected because it is very small compared to the linear polarization. It could, however, provide information on a planet’s atmosphere and surface, and on the presence of life, because homochiral molecules that are the building blocks of life on Earth are known to reflect...journal article 2018
