When this conference is held in North America, it is essentially The Millimeter Wave Conference. Thirty of the thirty-six sessions lie exclusively in the realm of millimeter waves, that is, 35 to 300 GHz. Measures are being devised by the Program Chair to increase the submillimeter component, but his appeal to the submillimeter scientists remains his strongest measure. A glance at the program shows that we have our usual Millimeter Wave Week and our usual Free Electron Laser and Gyrotron Week. But we now have another symposium on millimeter wave measurement techniques applied to the characterization of materials and the tabulation of their millimeter wave properties. Another new, and growing, component is the Microwave-Optical Interactions. Symposia.
