In conjunction with the 2013 International Microwave Symposium, ARFTG will hold its 81st Microwave Measurement Conference at the Grand Hyatt in Seattle, WA USA, June 7th, 2013. Beyond the focus topic of Metrology for High-Speed Circuits and Systems, technical papers describing original work in all areas of microwave and millimeter wave measurement are solicited. Other topics include, but are not limited to:  Linear and Nonlinear Vector Network Analysis  Multiport and Differential Measurement  On-Wafer Microwave Measurement  Emerging Technologies (RF-MEMS, CNT Devices, etc…)  Nondestructive In-Circuit Testing  Complex Waveform Analysis  Wideband Measurement for High-Speed Communication Systems  Other areas of microwave and millimeter wave measurement
