Abstract
An electrical filter system includes a transmission line and three or more separated photonic bandgap (PBG) structures positioned successively therealong.
Claims14
An electrical filter system, comprising:
- a transmission line for supporting electromagnetic wave transmission therealong;
- and
- at least three photonic bandgap (PEG) structures positioned successively along said transmission line with a gap separating adjacent ones of said PBG structures.
An electrical filter system, comprising:
- a transmission line for supporting electromagnetic wave transmission therealong;
- and
- a multi-stage photonic bandgap (PBG) resonator defining at least two pair of single-stage PBG resonators positioned successively along said transmission line.
An electrical filter system, comprising:
- a transmission line for supporting electromagnetic wave transmission therealong;
- and
- at least three photonic bandgap (PBG) structures with a gap separating adjacent ones of said PBG structures, said PBG structures positioned successively along said transmission line to control pass-band frequency attributes of said electrical filter system.
