Abstract
In this paper, the authors present the transmission line (TL) realization of
one-dimensional subwavelength resonator formed by a pair of conventional
right-handed material (RHM) and left-handed material (LHM). In such a resonator, a
novel resonant mode with the resonant frequency depending on the length ratio of the
RH/LH TL sections occurs as a consequence of the full phase compensation due to the
backward wave in the LH TL section. The theoretical circuit-model analyses are
supported by simulation and experimental evidence on resonators with different
RH/LH length ratios.
Keywords: Transmission line (TL), Subwavelength resonator, Left-handed material
(LHM), Phase compensation.
1 Introduction
Left-handed materials (LHMs), first investigated theoretically by Veselago [1], have received
substantial attention in the scientific and engineering communities. The unique properties of these
metamaterials are
