Abstract:
Using transfer matrix method,the transmission spectra of one-dimensional photonic crystal
(AB)m(BACAB)n(BA)m
 results show that in the
of double positive and negative
medium,all the bands of photonic crystal(BACAB)n were situated in the band gaps of photonic crystal
(AB)m(BA)m
constitute
the structure
of photonic quantum well with the symmetric central frequency
wo/
symmetric local
resonance
transmission peak appears in the transmission spectra of photonic
quantum well and shows obvious spectra quantization numbers
and positions
of
transmission
peaks
Can
be
adjusted by controlling竹,and
the
structures of transmission spectra of double positive
and
negative
medium
same,but the bandwidth and
clearance
of the latter is characteristics
