Summary:A new set of applicators dedicated to the exposition of giant vesicles, cells and spheroids to high power microwave pulses have been developed in order to maximize and optimize the E-field coupling in the Device Under Test (DUT) with the intention to harness the electromagnetic experimental conditions. These applicators are simultaneously characterized by low return loss(when charged by the sample under test)thus easing illumination experimentations. We particularly focus here on the implementation of two novel ideas which enable to enhance the electrical performances of the applicators. The first is based on a volume extension to obtain a better E-field homogeneity; the second lies on the use of a half wavelength filter in the case of narrow band signals. The development of these applicators takes place in a largest project which aims at identifying beneficial and/or hazardous non thermal effects of high power microwave pulses on living organisms.
