The Most Complete, Up-to-Date Coverage of the Finite Element Analysis and Modeling of Antennas and Arrays

Aimed at researchers as well as practical engineers—and packed with over 200 illustrations including twenty-two color plates—Finite Element Analysis of Antennas and Arrays presents:

  • Time- and frequency-domain formulations and mesh truncation techniques

  • Antenna source modeling and parameter calculation

  • Modeling of complex materials and fine geometrical details

  • Analysis and modeling of narrowband and broadband antennas

  • Analysis and modeling of infinite and finite phased-array antennas

  • Analysis and modeling of antenna and platform interactions

Recognizing the strengths of other numerical methods, this book goes beyond the finite element method and covers hybrid techniques that combine the finite element method with the finite difference time-domain method, the method of moments, and the high-frequency asymptotic methods to efficiently deal with a variety of complex antenna problems.

Complemented with numerous examples, this cutting-edge resource fully demonstrates the power and capabilities of the finite element analysis and its many practical applications.
