                         management of electronic devices with high-density heat 
                         dissipation. In these two-phase thermal devices, the key component 
                         is the capillary structure (CS) that pumps the working fluid using 
                         the capillary forces generated by the meniscus, which is formed 
                         due to evaporation. The performance of the LHP and the HP depends 
                         greatly on the internal structure and external configurations of 
                         the CS. However, there is not enough experimental and theoretical 
                         data on the optimization of the capillary structures of 
                         evaporators. The {"}inverted meniscus{"} scheme is the usual 
                         configuration for Loop Heat Pipes (LHP) but not for Heat Pipes 
                         (HP), which use the {"}classical{"} scheme. This paper presents 
                         the results of extensive experimental investigations on the 
                         optimization of the physical and geometrical parameters of the 
                         flat CS including thickness, configuration and size of vapor 
                         grooves, for different CS materials and working fluids. 
                         Additionally, the paper presents a comparative study between the 
                         {"}classical{"} and the {"}inverted meniscus{"} schemes of 
                         vaporization. Based on the obtained results, two examples of 
                         evaporators have been designed and evaluated.",
