Electromagnetism, radio-frequencies and microwaves

All physical electrical devices involve the interaction of electro-magnetic fields. The higher the frequency at which a device operates, the smaller the wavelength of the electromagnetic fields involved and the larger the devices are relative to a wavelength. Also, the electromagnetic phenomena are used in different ways than at lower frequencies. Thus, we need to develop in-depth efficient circuit modelling tools and measurement techniques specifically suited to the components that make terrestrial wireless, satellite, and optical communications networks possible. This includes developing advanced electro-magnetic and circuit simulation CAD tools that help with the design, simulation and optimization of devices and components for use in communication systems.

Microwave equipment such as cellular phones, cordless computer peripherals, indoor and outdoor security systems, positioning systems for cars and airplanes, satellite links and more is now part of our daily life. RF/microwave and optical devices are also used in industrial production lines, medical technologies and transport systems. Currently, demands for smaller size and weight, as well as accessibility to services such as text messaging, email, Internet and photo and video cameras, to name a few, are creating new challenges for RF/microwave engineers. Integrating so many different features in a single device means multi-task design, requiring experienced designers with both theoretical and experimental technical skills.
