Here, we report a microwave applicator for rapid heating of small samples by highly uniform irradiation. It features an anechoic chamber, a 24-GHz microwave source, and a linear-to-circular polarization converter. With a rather low energy efficiency, such an applicator functions mainly as a research tool. This paper discusses the significance of its special features and describes the structure, in situ diagnostic tools, calculated and measured field patterns, and preliminary heating tests of the overall system. © 2014 IEEE.[SDGs]SDG7Anechoic chambers; Applicators; Circular polarization; Energy efficiency; Energy utilization; Industrial research; Irradiation; Microwave irradiation; Circularly polarized; Field uniformity; Microwave applicators; Microwave sources; Polarization converters; Scientific researches; Scientific studies; Situ diagnostics; Terahertz wavesconference paper10.1109/IRMMW-THz.2014.69562642-s2.0-84911973899https://www2.scopus.com/inward/record.uri?eid=2-s2.0-84911973899&doi=10.1109%2fIRMMW-THz.2014.6956264&partnerID=40&md5=8f20455a83ee7a6a113239a9a08cb985
