We present a dual-mode resonator operating at/near 94 GHz (W-band) microwave frequencies and supporting two microwave modes with the same field polarization at the sample position. Numerical analysis shows that the frequencies of both modes as well as their frequency separation can be tuned in a broad range up to GHz. The resonator was constructed to perform pulsed ELDOR experiments with a variable separation of pump and detection frequencies up to Delta nu = 350 MHz. To examine its performance, test ESE/PELDOR experiments were performed on a representative biradical system. (C) 2011 Elsevier Inc. All rights reserved.
