Summary: This paper proposes an ultrawideband planar monopole array antenna with excellent stealth performance by using a combination of traditional copper film and novel phase transition film vanadium dioxide (VO2). By carefully designing the antenna shape and using an innovative combination of VO2+Cu films, the tradeoff between radiating efficiency and reducing radar cross section (RCS) is optimized, resulting in a decreased gain of only 0.4 dBi and a reduced monostatic RCS of about 9 dB.

Summary: This paper characterizes the resistively loaded bowtie antenna (RBA) in terms of both frequency and time domains for short pulse radiating and sensing impulse radio ultra-wide band applications. The design procedures of RBA are implemented to optimize it for short-range target sensing applications. The figure of merit is introduced to reflect the short pulse radiating characteristic in the design procedures. The performance of the developed RBA is evaluated using evaluation factor (EF) and pulse distortion factor (DF), resulting in EF of 149 and DF of 0.12. The RBA's performance is investigated from the perspective of short-range impulse radar characteristics. The proposed RBA is experimentally demonstrated to be suitable for short-range impulse radar applications.

Summary: A novel surrogate modeling approach for frequency-reconfigurable antennas is proposed, based on rigorous mathematical derivation. The approach converts discrete data from CAD simulation into a surrogate model through nonlinear overdetermined system solution, complex field optimization, and multidimensional continuous space interpolation. The feasibility, effectiveness, and precision of the approach are demonstrated using a reconfigurable UWB antenna with a tunable notch band as an example. The proposed surrogate model is flexible and can meet strict requirements in complex scenarios, making it a good candidate for the interface standard between a reconfigurable antenna and signal processing part in a cognitive radio system.

Summary: When high-energy and high-power lasers interact with matter, they can generate transient electromagnetic pulses (EMPs) that may pose a significant danger to electronic devices. Understanding the origin and distribution of these electromagnetic fields is crucial for the safe operation of laser facilities and potential applications. Various mechanisms, such as target positive charging and laser-plasma interactions, can generate intense electromagnetic fields during laser-matter interactions.

Summary: Time-Of-Flight (TOF) methods are effective for detecting particles accelerated by laser-plasma interactions, but have limitations in high energy and intensity laser experiments due to the generation of high-energy ions and significant levels of ElectroMagnetic Pulses (EMPs). A novel diagnostic method using stacked diamond detector structure and TOF technique is described for characterizing protons accelerated by intense laser pulses, offering high sensitivity, resolution, radiation hardness, and signal-to-noise ratio in heavily EMP-affected environments. Detailed study on a single module of the stack in a highly EMP-polluted environment is presented, along with calibrated spectra of accelerated protons from an experiment with the femtosecond Flame laser.

Summary: This study investigates the potential of carbon nanofoams produced with pulsed laser deposition (PLD) technique as ablators for direct-drive fusion. Hydrodynamic numerical simulations show that PLD nanofoams exhibit higher pressure at the shock front compared to solid-density carbon, making them potential candidates for ablation materials in fusion capsules.
