Abstract:

The ability to utilize a single cylindrical dielectric resonator to realize a multi-functional device is presented. Simultaneous excitation of multi-independent modes of a single dielectric resonator is used for filtering and oscillating as well as radiating purposes is discussed. A design of a dielectric resonator antenna in a polarization filtering cavity for dual function applications is studied where a cylindrical dielectric resonator is enclosed by a hypothetical resonant cavity that acts as a shielding for the resonating mode while transparent for the radiating mode. A possible application of this device is a receiving antenna at the frequency of the radiating mode and can incorporate a local oscillator operating at the resonant frequency of the resonating mode.

In this presentation, ANSYS HFSS – a full-wave 3D FEM electromagnetic simulation – is used to perform simulations of the dielectric resonator.

New Local Chapter Administrative Committee members are needed.  Really.  If you are reading this sentence, then we need you to help us in the Chapter. 

Join us in planning the next lecture series.  Please volunteer... everyone has something to offer.  The next administrative meeting will be held soon.

Please contact 2012-13 Chapter Chair Tony Ivanov
