Engineering The Invisible: Frequency Selective Surfaces In Action
– Advertisement – While composed of sub-wavelength structures, Frequency Selective Surfaces are capable of manipulating electromagnetic waves—bending, filtering, or absorbing them across diverse communication and sensing applications. Is it shaping the future of adaptive electromagnetic environments? What if one could control the behaviour of electromagnetic waves—bending, absorbing, or filtering them—using surfaces thinner than a human…

Power Tips #136: Design an active clamp circuit for rectifiers at a high switching frequency
Introduction In vehicle electrical systems, a high- to low-voltage DC/DC converter is a reversible electronic device that changes the DC from the vehicle’s high-voltage (400 V or 800 V) battery to a lower DC voltage (12 V). These converters can be unidirectional or bidirectional. Power levels from 1 kW to 3 kW are typical, with…
