Electrically erasable programmable read-only memory (EEPROM) is a type of nonvolatile memory that enables users to repeatedly store and erase small amounts of data by applying a voltage pulse. EEPROM is often used as a storage medium in computers and mobile devices and has applications in devices like microcontrollers. To analyze the designs of EEPROM devices, engineers can turn to semiconductor simulation.

Circulators are a bit like traffic circles (also known as rotaries or roundabouts), where motion occurs in one direction only and each pathway doubles as an entrance and exit. In a circulator, however, the microwave signal always exits at the next available port. This characteristic makes circulators useful for applications that involve coupling transmitters and receivers to common antennas. To ensure that circulators function successfully, electrical engineers can study their designs with electromagnetics simulation.

If you were to take apart almost any modern electronic product, you would find a printed circuit board (PCB). A closer look at this common component reveals a pattern of copper lines on its surface. These conducting lines can be created using a process called electrodeposition, which modifies device surfaces via electrochemical reactions. To enhance electrodeposition techniques for circuit board manufacturing, engineers can use numerical modeling.

Silicon planar devices, imaging sensors, and microprocessors often include a metal-oxide-silicon (MOS) capacitor. To ensure that these devices perform as expected in an application, engineers can accurately analyze their designs using simulation. With the Semiconductor Module, an add-on product to the COMSOL Multiphysics® software, there are multiple methods to do just that…

What sparked Blaise Pascal’s interest in mathematics? One possibility is that when Pascal’s father tried to put off teaching it to his son, it didn’t go as planned. Instead, the delay piqued Pascal’s interest and he wound up teaching himself mathematics, developing an early fascination with the subject. Today, Blaise Pascal is known for his work in mathematics as well as in other areas, such as philosophy and theology.

Mount Erebus, one of Earth’s most remote volcanoes, sits covered in snow and ice. These chilly surroundings can be misleading, as Mount Erebus has another claim to fame: It’s the most active volcano in Antarctica. One option for mapping its magma flow is with a technique called magnetotellurics (MT), which measures the electrical resistivity of Earth’s crust. To study and improve MT, engineers can analyze its performance with electromagnetics simulation.

What’s at the center of the earth? To answer this question, Inge Lehmann, a Danish geophysicist and seismologist, used seismic waves generated by earthquakes to study the middle of the planet. Her results revealed what truly lies at the center of the earth: a solid inner core inside a molten outer core.

Born to a family with a longstanding military lineage, it’s no surprise that Jean-Charles de Borda joined the French army and navy. He was a man of many trades and is also seen as a surveyor, mathematician, political scientist, and physicist. Due to his wide interests, Borda contributed to the advancement of fluid mechanics, geodesy, navigation, and more during his lifetime.

Picture a classroom filled with students. At the front, a teacher discusses room acoustics, including the underlying theories and acoustics phenomena involved. To help students visualize these concepts, the teacher has created a simulation app. This app, which is accessible through a web browser, enables students to dynamically alter parameters and see the results, creating a vivid learning experience. At the Technical University of Munich (TUM), several such apps are already being used, providing benefits to teachers and students alike…
