A sort of Left-handed materials (LHMs), which are called PLHMs, were designed by inserting parallel LC resonance elements (PLCREs) into traditional LHMs as isomerization units. The effects of PLCREs were studied numerically by evaluating the transmission spectra of microwaves with both Finite-difference Time-domain (FDTD) and CST simulator. A brand-new pass-band, which is tunable from 2.0GHz to 7.0GHz by varying the capacitance and inductance of the PLCREs, was detected in a lower frequency range. In addition, the PLCREs with capacitors and inductors of different parameters could shift and expand the basic left-handed pass-band of PLHMs. With these novel phenomena, we could achieve the quantitative controllability to design LHMs with desired transmission properties by varying the electrical parameters of PLCREs.
