When it’s Impossible to Take Actual Measurements, Multiphysics Provides the Answers

Simon Chiartano,
Terres Réfractaires du Boulonnais (TRB), France

To contain splashes and provide protection at plants where metal is fabricated, blast furnace runners need a roof made of cast iron and concrete. Terres Réfractaires Du Boulonnais, a manufacturing company in France, has hundreds of blast furnaces with a short functional lifespan, so engineers need to design roof runners as economically as possible while maintaining overall safety. During the ...

A 100-Fold Improvement in Lithography Resolution Realized with a 150-Year-Old “Perfect Imaging” System

Juan Carlos Miñano and Dejan Grabovičkić
Cedint Polytechnic University of Madrid

The idea of "perfect imaging", that is a resolution less than the wavelength of light producing the image, was first proposed in the mid-19th century by famed Scottish physicist James Clerk Maxwell. For the next 150 years, it was widely believed that such was impossible due to the fact that light diffracts around points that are the same size or smaller in wavelength. Then, in 2009, Ulf ...

Analysis of Spiral Resonator Filters

S.P. Yushanov, J.S. Crompton, and K.C. Koppenhoeffer
AltaSim Technologies

As the world becomes more digital, there is growing demand for advanced wireless systems. Increasingly high data rate transmission systems mean that components like microwave filters must fit into smaller and smaller spaces, and multiple filters need to be integrated into compact designs. Engineers are challenged to meet a filter's specific passband frequencies and quality requirements within the ...

Picking the Pattern for a Stealth Antenna

F. De Vita, S. Di Marco, F. Costa and P. Turchi
Altran, Italy

Stealth airplanes and ships avoid radar detection by optimizing the shape of surfaces to reflect away from the radar source or absorb its energy. Yet, if a ship or aircraft’s antenna for communication purposes is to operate properly, it cannot be completely covered up. This makes it one of the remaining components with a large radar cross section and can essentially destroy the overall ...

Multiphysics Software, a Versatile, Cost-Effective R&D Tool at Sharp

Chris Brown
Sharp Laboratories of Europe, UK

There are several kinds of technology that designers at Sharp Laboratories of Europe work to create. From LED lighting, displays, and microfluidic lab-on-a-chip technology, to complex energy systems used in various devices, Sharp needed a new approach to finding the best designs. COMSOL Multiphysics and its add-on products provided the versatility to augment Sharp's research and development in ...

Silent Air Cooling: A New Approach to Thermal Management

Nels Jewell-Larsen,
Tessera Technologies, CA, USA

Removing heat from electronic devices is a necessity that up until now was achieved by rotary fans. Tessera, a company that delivers innovative miniaturization technologies and products for next-generation electronic devices, developed a replacement for rotary fans that can satisfy demanding space and noise constraints. They designed a silent air cooling system that uses an electric field to ...

Multiphysics Simulations Help Track Underground Fluid Movements

A. Haas, H. Mahardika, M. Karaoulis, and A. Revil
Colorado School of Mines, USA

Combining acoustic and electromagnetic analyses helps scientists to more efficiently measure and survey subterranean regions. Acoustic waves can travel long distances, but have limitations when it comes to providing details about formation properties, and cannot be used to identify the liquids flowing through them. Electromagnetic waves do not propagate as far as acoustic waves, but can identify ...

Highly Accurate Li-ion Battery Simulation

Mikael Cugnet
French Atomic and Alternative Energy Commission

Battery management systems (BMSs) are designed to protect the batteries and predict their charge level. They use circuit models often derived from electrochemical impedance spectroscopy (EIS) measurements to construct an equivalent circuit model (ECM) that consists of resistors and capacitors connected both in series and in parallel. Yet, ECMs do not provide any information about important cell ...

Multiphysics Simulation Helps Miele to Optimize Induction Stove Designs

Christian Schröder
mieletec FH Bielefeld

Holger Ernst

The induction stove was designed to meet a consumer need for better precision and speed than traditional stoves. Designers were tasked with improving the energy efficiency of the induction coils-stovepot interaction considering both the thermal and electromagnetics of the system. Miele, a world leader in domestic appliances and commercial machines, along with researchers from mieletec FH ...

Modeling the Electrochemistry of Blood Glucose Test Strips

Stephen Mackintosh
Lifescan Scotland

Lifescan Scotland is a medical device company that designs and manufactures blood glucose monitoring kits for the global diabetes market. These involve the self-monitoring of blood glucose levels through specialized monitoring systems and test strips that comprise of a plastic substrate, two carbon-based electrodes, a thin dry reagent layer, and a capillary volume where the blood is ...
