Don't Miss these Interesting Technical Sessions at IMS 2019

The IEEE MTT International Microwave Symposium (IMS) is the premier annual international meeting for technologists involved in all aspects of microwave theory and practice. It consists of a full week of events, including technical paper presentations, workshops, and tutorials, as well as numerous social events and networking opportunities. This year the event will take place in Boston from 4-6 June. 

Here is the list of a few interesting technical sessions at IMS 2019:

Chair: Julio Navarro, Boeing

Co-chair: Glenn Hopkins, Georgia Tech

Chair: Valentina Palazzi, Università di Perugia

Co-chair: Weijing SU, Google

Location: 153AB

Abstract: This session highlights recent advances in 3D printed RF components and interconnects. A squeezed spherical cavity is presented that uses a rectangular slot for higher order mode suppression. Then an integrated transition between suspended rectangular coaxial lines to rectangular waveguide is shown. Novel interconnects including a laser-enhanced direct-printed CPW line operating up to 110 GHz is demonstrated, while a coaxial-to-two parallel wireline is tested up to 40 GHz. The session concludes with a novel helical-based microstrip transmission line enabling phase implementation in fixed length structures.
