These modes are typically realized as tightly confined\n\t\t\t\t\tsurface waves in photonic crystals or materials with topologically\n\t\t\t\t\tnontrivial bandgaps. Here, we show that a structure comprising a\n\t\t\t\t\tmagnetized semiconductor layer sandwiched between electro- and\n\t\t\t\t\tmagneto-opaque materials can support unidirectional bulk\n\t\t\t\t\tmagnetoplasmons at terahertz frequencies, in which all field\n\t\t\t\t\tcomponents maintain constant amplitudes within the core layer. These\n\t\t\t\t\tmodes exhibit modal properties that are independent of the core\n\t\t\t\t\tthickness, allowing the modal spot to extend over several wavelengths.\n\t\t\t\t\tNumerical simulations further confirm their immunity to\n\t\t\t\t\tbackscattering. By combining the tunability of modal spot with the\n\t\t\t\t\trobustness of unidirectional propagation, these unidirectional bulk\n\t\t\t\t\tmodes offer more degrees of freedom for the manipulation of terahertz\n\t\t\t\t\twaves.<\/jats:p>","DOI":"10.1364\/ol.579716","type":"journal-article","created":{"date-parts":[[2025,12,10]],"date-time":"2025-12-10T14:00:11Z","timestamp":1765375211000},"page":"249","update-policy":"https:\/\/doi.org\/10.1364\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Unidirectional bulk magnetoplasmons at terahertz frequencies"],"prefix":"10.1364","volume":"51","author":[{"ORCID":"https:\/\/orcid.org\/0009-0006-0350-2868","authenticated-orcid":true,"given":"Ye","family":"Tian","sequence":"first","affiliation":[{"name":"Zhejiang University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qingyu","family":"Li","sequence":"additional","affiliation":[{"name":"Zhejiang University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-8131-0657","authenticated-orcid":true,"given":"Hongyan","family":"Lou","sequence":"additional","affiliation":[{"name":"Zhejiang University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Shiqing","family":"Li","sequence":"additional","affiliation":[{"name":"Zhejiang University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3602-515X","authenticated-orcid":true,"given":"Linfang","family":"Shen","sequence":"additional","affiliation":[{"name":"Zhejiang University of Technology"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"285","published-online":{"date-parts":[[2025,12,30]]},"reference":[{"key":"ol-51-2-249-R1","doi-asserted-by":"publisher","first-page":"494","DOI":"10.1103\/PhysRevLett.45.494","type":"journal-article","volume":"45","author":"Klitzing","year":"1980","journal-title":"Phys.
