A potential energy surface scanning method and system for the analysis of molecular conformational space includes: judge whether the molecule has adjacent dihedral angles. If there are adjacent dihedral angles, judge whether the adjacent dihedral angles are coupled by QM calculations. If they are judged not to be coupled, then perform one-dimensional potential energy scanning. If judged to be coupled, then perform MM coupling judgment. If the MM calculations determine that the adjacent dihedral angles are not coupled, a one-dimensional potential energy surface scan is performed. If the MM calculation judges that the adjacent dihedral angles are coupled, calculate the coverage of the extreme points on the two-dimensional potential energy surface by the combination of extreme points obtained by scanning the individual one-dimensional potential energy surfaces of the two dihedral angles according to the MM scanning result. If the coverage is good, then perform one-dimensional potential energy surface scanning.

A radio frequency (RF) device includes an RF transceiver, an RF antenna, and a magnetic signal detector. The RF is selected to be in the very high frequency (VHF), ultrahigh frequency (UHF), or super high frequency (SHF) bands such that the shielding effect is reduced and the RF device can be configured as a SIM card disposed inside a cellular phone with an increased RF communication range. The magnetic signal detector is used to sense a magnetic field signal from an RF reader, which includes an RF transceiver, an RF antenna, and a magnetic signal transmitter. The longer communication range afforded by the VHF, UHF, or SHF bands is reduced by the sensing of the magnetic field, thereby providing a communication range control, while the RF device and the RF reader exchange information through the RF channel with improved security as a result of the range control.
