Unlike wood or copper or silicon, though, topological insulators (TIs) are an exotic state of matter that is conductive on the surface, but not in the bulk. Such unique material properties have great scientific implications and could be of use in a range of technologies, including wireless communications, radar and quantum information processing.<\/p>\n<p>                                                                                Through a collaborative effort, the research labs of Aravind Nagulu, assistant professor in the Preston M. Green Department of Electrical &amp; Systems Engineering at Washington University in St. Louis, and colleagues from Columbia University and the City University of New York&#8217;s Advanced <a href=\"https:\/\/buradabiliyorum.com\/en\/category\/sciencee\/\" data-internallinksmanager029f6b8e52c=\"5\" title=\"Science\" target=\"_blank\" rel=\"noopener\">Science<\/a> Research Center have demonstrated the first implementation of an electromagnetic topological insulator on an integrated chip.<\/p>\n<p>The collaborative project&#8217;s findings were published May 2 in the journal <i>Nature Electronics<\/i>.<\/p>\n<p>&#8220;Topological Insulators have very interesting properties and are useful on their own. However, their real potential emerges when they are coupled with non-reciprocal properties,&#8221; Nagulu said.<\/p>\n<p>Non-reciprocity ensures one-way propagation to the electromagnetic (EM) waves. This property can be used in full-duplex communication, a method that allows for transmission and receipt of data using the same frequency at the same time in an efficient manner, thereby doubling the spectral capacity. Additionally, TIs with non-reciprocal properties prevent the decay of signal strength due to back-scattering if the wave comes into contact with any deformities or irregularities within the medium.<\/p>\n<p>The team was able to use precisely engineered time-modulation of transistor switches to achieve non-reciprocity and topological insulating properties on a standard semiconductor IC without the need for exotic materials or extreme conditions.<\/p>\n<p>This tiny integrated chip couples the exotic fields of TIs with real-world application. It can also re-route the EM waves on demand by reconfiguring the individual unit-cells in the lattice, creating a fabric that flexibly and arbitrarily routes EM waves. The team demonstrated how a reconfigurable integrated circuit can be used for emerging 5G wireless applications such as multi-antenna full-duplex wireless communications and multi-antenna impulse radar.\n                                                                                                                        <\/p>\n<hr\/>\n<div class=\"article-main__explore my-4 d-print-none\">\n<p>                                            Engineers develop the first on-chip RF circulator that doubles WiFi speeds with a single antenna\n                                        <\/p><\/div>\n<hr class=\"mb-4\"\/>\n<div class=\"article-main__more p-4\">\n                                                                                                <strong>More information:<\/strong><br \/>\n                                                Aravind Nagulu et al, Chip-scale Floquet topological insulators for 5G wireless systems, <i>Nature Electronics<\/i> (2022).  <a rel=\"nofollow noopener\" target=\"_blank\" data-doi=\"1\" href=\"https:\/\/dx.doi.org\/10.1038\/s41928-022-00751-9\">DOI: 10.1038\/s41928-022-00751-9<\/a><\/p><\/div>\n<div class=\"d-inline-block text-medium my-4\">\n                                                Provided by<br \/>\n                                                                                                    Washington University in St. Louis<br \/>\n                                                                                                        <a rel=\"nofollow noopener\" target=\"_blank\" class=\"icon_open\" href=\"http:\/\/www.wustl.edu\/\"><br \/>\n                                                        <svg>\n                                                            <use href=\"https:\/\/techx.b-cdn.net\/tmpl\/v2\/img\/svg\/sprite.svg#icon_open\" x=\"0\" y=\"0\"\/>\n                                                        <\/svg><br \/>\n                                                    <\/a><\/p><\/div>\n<p>                                        <!-- print only --><\/p>\n<div class=\"d-none d-print-block\">\n<p>                                                 <strong>Citation<\/strong>:<br \/>\n                                                 New tech can double spectral bandwidth in some 5G systems (2022, May 11)<br \/>\n                                                 retrieved 11 May 2022<br \/>\n                                                 from https:\/\/techxplore.com\/<a href=\"https:\/\/buradabiliyorum.com\/en\/category\/news\/\" data-internallinksmanager029f6b8e52c=\"2\" title=\"News\" target=\"_blank\" rel=\"noopener\">news<\/a>\/2022-05-tech-spectral-bandwidth-5g.html<\/p>\n<p>                                            This document is subject to copyright.
