Evanescent growth and tunneling through stacks of frequency-selective surfaces
Evanescent growth and tunneling through stacks of frequency-selective surfaces
The presence of wave tunneling and the "growing evanescent envelope" for field distributions in suitably designed, periodically layered stacks of frequency selective surfaces (FSS) is discussed in this letter. It is known that a slab of double-negative (DNG) or left-handed metamaterial sandwiched between two vacuum half-spaces may lead to "growing" …
