Abstract :
The IEEE Microwave Theory and Techniques Society (MTT-S) has joined a number of other IEEE societies in the IEEE Online Periodicals and Research Area (OPeRA, formerly known as JOLLY). As a result, the current volumes of MTT-S Transactions and Letters are now available on-line to MTT-S member subscribers. New issues become available electronically on the same day as the paper versions are published, thus permitting researchers with long delivery lags to become current electronically. OPeRA only retains issues for one year. Older articles must be obtained through bibliographic searching, as described below. The on-line journals are identical in content and layout to the published paper journals. Members with access to a 600-dpi laser printer will probably find their downloaded hard copy version to be far superior to a photocopy made from the paper journal. Direct on-line viewing of articles is possible if your browser supports Adobe Acrobat Reader?? plug-ins, but the result is not as clear on the screen as it is in subsequent hard copy.
