Abstract
The use of transformation electromagnetics for microwave applications is presented. Implementation of non-standard devices such as microwave antennas and waveguide tapers proposed by the Institut d’Electronique Fondamentale at the University of Paris-Sud are reviewed. The operating principle and the respective coordinate transformation of each device is presented and numerical simulations are performed to verify the theoretical formulations. The method to obtain constitutive electromagnetic parameters mimicking the calculated transformed space is detailed and confirmed by full-wave simulations performed using discrete material parameter values and by measurements performed on fabricated metamaterial-based prototypes. The results show that transformation electromagnetics is very interesting for the design and realization of high-performance non-standard devices.
