We present a hybrid coupling scheme of a magnetic toroidal and electric dipole metasurface with suppressed radiation loss,which can produce the tunable plasmon-induced transparency(PIT)with an enhanced slow-light effect in the terahertz *** terahertz metasurface is constructed by nesting a dual-split ring resonator(DSRR)inside a ring resonator(RR)to exploit the destructive coherence of hybrid electromagnetic mode coupling at the PIT *** polarization-dependence excitation performs the active tunability of a PITinduced group slowing down by rotating the polarization angle,experimentally achieving a maximum group delay of 3.5 ***,the modified terahertz metasurface with a four-split ring resonator(FSRR)nested in an RR is prepared on photoconductive silicon,demonstrating the pump-controllable group delay effect at the PIT *** large group delay from 2.2 to 0.9 ps is dynamically tunable by adjusting the pump *** experimental results are in good accord with the theoretical simulations.

Western Yunnan is located in the southeast Himalayas, with well-developed faults and abundant high-temperature geothermal resources. In the western Yunnan geothermal fields, the hydrochemical and isotopic characteristics of geothermal fluids are studied and analyzed, elucidating the genetic model of magmatic high-temperature geothermal systems, and revealing the hydrochemical processes and genesis of geothermal water during the circulation process. The Rehai geothermal water type is mainly HCO3 Cl-Na. The high Cl content of geothermal water comes from the supply of magmatic water, while Na, K, and HCO3 mainly come from the leaching of feldspar minerals by mantle-derived CO2. Water hydrogen and oxygen isotopes indicate the source of atmospheric precipitation, while Rehai hot spring water shows an "18O shift". It is related to the mixing of magmatic water and the interaction between water and rock. According to the Na-K cation thermometer, among numerous geothermal fields of the western Yunnan region, the deep reservoir temperature of the Rehai geothermal field is the highest, reaching 260 ℃. The Rehai geothermal water undergoes deep circulation and obtains deep heat after being recharged by atmospheric precipitation infiltration in the metamorphic rock area of the Gaoligongshan group located in the northeastern mountainous area. Rising along the fault, exposed as a hot spring at the surface. Copyright 2024 ARMA, American Rock Mechanics Association.
