When the  grating is in the insulating state, efficient cross\u2010polarization conversion in the frequency range of 3.88\u20135.5\u00a0THz is achieved, with a maximum conversion efficiency exceeding 0.98. Within the frequency ranges of 2.31\u20132.61\u00a0THz and 6.42\u20136.68\u00a0THz, the linearly polarized (LP) wave is efficiently converted to a circularly polarized (CP) wave. When the  grating is in the metallic state, the function of asymmetric transmission (AT) is realized, where the TMPMM can be utilized as a broadband isolator and half\u2010wave plate for an \u2010polarized wave and can also be utilized as a narrowband isolator and polarization conversion switch for a \u2010polarized wave. Under the forward incidence of CP waves, the TMPMM selectively transmits left\u2010 and right\u2010circularly polarized waves near 2.25\u00a0THz and 6.37\u00a0THz, respectively, achieving significant spin\u2010dependent polarization selection. Additionally, through simple temperature tuning, the proposed TMPMM enables dynamic control of AT, circular dichroism, and ellipticity. All these multifunctional and tunable properties are realized via temperature variation without altering the structural geometry parameters.<\/jats:p>","DOI":"10.1002\/nap2.70175","type":"journal-article","created":{"date-parts":[[2026,6,19]],"date-time":"2026-06-19T13:44:48Z","timestamp":1781876688000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Transmissive
