Metamaterials: Theory, Design and Applications focuses on the most recent research activity in metamaterials, taking a reader beyond previously covered areas like left-handed materials (LHM) and negative index materials (LIM). Some new developments covered in the book include a rapid design method for inhomogeneous metamaterials, microwave and RF applications of metamaterials and dynamic metamaterial...
The finite-difference time-domain (FDTD) method was used to investigate the effects of finite left-handed material (LHM) slab and mismatch on the energy localization using the LHM slab. It is shown that both the finite size of LHM slab and the mismatch of constitute parameters can lead to the energy leakage, and the mismatch has a stronger effect
In this work, we first focus our attention to the physical properties of electromagnetic (EM) wave excited by a 3D horizontal electric dipoles (HED) in the lossy and mismatched left-handed material (LHM). Then we study the EM wave and energy localization using the lossy LHM slab lens
In this paper, we make use of the special physical characteristics of novel artificial left-handed materials (LHM) to realize the super resolution. One of the most attractive features of LHM is the amplification of evanescent waves. Using such a feature, it has been shown that strong surface waves can be excited near the boundaries of LHM slab with small loss. We investigate the possibility to enhance...
In this work, an accurate model has been developed based on the equivalence principle for the EM scattering by a dielectrically coated PEC body. The original CFIE is replaced by the modified CFIE to reduce the computational time without losing accuracy. Theoretical analysis and numerical results are given to validate the proposed formulations
In this paper, a delay-line loaded Vivaldi TSA has been realized, which is fed by a microstrip line. The slot-line is etched on the ground plane of the microstrip line, and one of its sides is a narrow open port and the other side is a gradually widening slot as radiating port. At the ends of tapered flare slot, there are about 1 m long delay-lines. The unvarnished currents will go along the delay-lines...
