Design of a High-Power UWB Antenna Incorporating a Solid Dielectric for Electronic Warfare Applications

In this paper, a high-power ultrawideband antenna is presented for the purpose of remotely neutralizing improvised explosive devices. The developed antenna has a bandwidth between 230 MHz and 2 GHz, as well as a maximum realized gain of 18.7 dB. The antenna structure incorporates a solid dielectric (HDPE 1000) so that it can be powered, without risk of a possible breakdown voltage, by a Marx generator which delivers a bipolar pulse with a peak amplitude of +/−250 kV, a rise time of 170 ps, and a duration of 1 ns. The radiated electric field obtained in simulation is, respectively, 1 MV/m peak and 126 kV/m peak at a distance of 1 m and 10 m.

IntroductionThe Chinese Role 2 Hospital (CHN-Role 2H) Medical Treatment Facility (MTF) was founded in July 2013 as part of the Chinese commitment to Multidimensional Integrated Stabilization Mission in Mali (MINUSMA). It provides medical care for approximately 5200 personnel of the whole Sector East of MINUSMA including UN military personnel, UN police and UN civilian staff. The aim of this study was to determine the orthopaedic surgical activity over a 4-year period to facilitate the training of future Chinese military surgical teams.Materials and methodsSurgical records of all patients operated on at the CHN-Role 2H between 28 March 2014 to 28 March 2018 were identified, and all orthopaedic activity were analysed.ResultsDuring this period, 1190 patients underwent 2024 surgical procedures. Orthopaedic procedures represented 961/2024 (47.5%) of all the procedures. Battle injury (BI) represented 43% of patients. Improvised explosive devices (IEDs) were responsible for 15.8 % casualties. Fractures (49%) and soft tissue injures (43%) were the most common injuries, with 61% of the fractures being open. Damage control surgery including debridement (23.52%) and external fixation (17.90%) were the most frequently performed interventions.ConclusionOrthopaedic surgery is the most frequently performed surgery in the CHN-Role 2H in Mali. The complexity and severity of injuries demonstrate the urgent need for tailored training and extended skill sets for deploying military orthopaedic surgeons.
