Curl cannot be employed in which one of the following?
  • a)
    Directional coupler
  • b)
    Magic Tee
  • c)
    Isolator and Terminator
  • d)
    Waveguides

Answer: d
Explanation: In the options a, b, c, the EM waves travel both in linear and angular motion, which involves curl too. But in waveguides, as the name suggests, only guided propagation occurs (no bending or curl of waves).

Waveguides

Waveguides are structures used to guide electromagnetic waves, typically in microwave and optical communication systems. Curl cannot be employed in waveguides due to their inherent nature and the way they function.
  • Directional coupler: Curl can be employed in directional couplers to analyze the electromagnetic fields and characteristics of the device.
  • Magic Tee: Curl can be used in analyzing the electromagnetic fields and signal propagation in Magic Tees, which are four-port microwave devices.
  • Isolator and Terminator: Curl can be employed in isolators and terminators to study the electromagnetic behavior and properties of these components.


In the case of waveguides, the electromagnetic fields and wave propagation within the structure are typically analyzed using different mathematical and computational techniques, such as boundary value problems and mode analysis. The use of curl in waveguides is not common or applicable due to the complex geometry and boundary conditions present in these structures.
Therefore, while curl may be utilized in various components and devices in microwave and optical systems, it is not typically used in the analysis or design of waveguides.
