Such security can be achieved by following three best practices identified in the paper:
As technology advances, the need to place larger numbers of electrical and electronic systems into automobiles has dramatically increased. To name a few, these systems include Control Area Networks (CAN), safety systems, communications, mobile media, infotainment systems including wireless headsets, DC motors and controllers. The physical size of these systems is greatly reduced because of the size and weight constraints involved with automotive design. These systems may be small, but it does not necessarily mean their electromagnetic emissions are too.
PCR is a technique widely used in molecular biology to produce millions of copies of a specific DNA sequence. PCR-based testing is used in the diagnosis of hereditary diseases, the identification of genetic fingerprints, and the detection and diagnosis of infectious diseases. PCR uses thermal cyclers to alternately heat and cool a DNA sample based on a predefined series of temperature steps to facilitate the amplification of the DNA.
By implementing microwave absorbent material, unwanted cavity resonances are effectively dampened to prevent microwave radiation in circuits where PC-board is used as a cover. Today, many microwave circuit designers are noticing that their circuits do not perform as well as predicted when they enclose them with circuit board covers. As a result, cavity resonances are set up inside the cavity, which changes the impedance conditions required for proper operation of some circuit elements. With operational frequencies increasing, this is becoming a prevalent issue in microwave circuit design.
Absorbers in the RF/microwave realm are materials that attenuate the energy in an electromagnetic wave. Absorbers are used in a wide range of applications to eliminate stray or unwanted radiation that could interfere with a system’s operation. Absorbers can be used externally to reduce the reflection from or transmission to particular objects and can also be used internally to reduce oscillations caused by cavity resonance. They can also be used to recreate a free space environment by eliminating reflections in an anechoic chamber.
