We propose a novel surface plasmon resonance sensor design based on a grapefruit photonic crystal fiber. In such a
sensor, phase matching between plasmon and a core mode is achieved by introducing microstructure into the fiber core.
Using the finite element method, the confinement loss of the fiber is calculated to measure the sensitivity of the sensor.
Simulation results show that this kind of sensor has an excellent effect, with the amplitude resolution to be as low as
2.88×10-5 RIU and the spectral resolution to be 6.67 ×10-5 RIU.

Using the finite element method to simulate THz photonic crystal fiber(PCF)transmission and sensing characteristics.
According to solid TPCF guidance, the refractive index, attenuation and relativity sensitivity were analyzed. And we
analyzed firstly the transformation of PCF hole-shape to the influence of sensing on THz wave region. Then we simulate
and calculate THz high density polyethylene PCF(HDPE-PCF) some parameters, at last the design considerations were given.
Terahertz(THz) transmission can be divided into passive transmission and active transmission, passive transmission
refers to atmospheric propagation, active transmission means not only transmission but also completing a function, so
also can be said functional transmission.Knowledge of the transmission of terahertz wave is very important for terahertz
technology and its applications. We analysis detailed the atmospheric propagation model of terahertz wave, propagation
effects, propagation equation, then carry out atmospheric propagation measurement system based on THz-TDS.
