AbstractNanophotonic devices with high densities are extremely attractive because they can potentially merge photonics and electronics at the nanoscale. However, traditional integrated photonic circuits are designed primarily by manually selecting parameters or employing semi-analytical models. Limited by the small parameter search space, the designed nanophotonic devices generally have a single function, and the footprints reach hundreds of microns. Recently, novel ultra-compact nanophotonic devices with digital structures were proposed. By applying inverse design algorithms, which can search the full parameter space, the proposed devices show extremely compact footprints of a few microns. The results from many groups imply that digital nanophotonics can achieve not only ultra-compact single-function devices but also miniaturized multi-function devices and complex functions such as artificial intelligence operations at the nanoscale. Furthermore, to balance the performance and fabrication tolerances of such devices, researchers have developed various solutions, such as adding regularization constraints to digital structures. We believe that with the rapid development of inverse design algorithms and continuous improvements to the nanofabrication process, digital nanophotonics will play a key role in promoting the performance of nanophotonic integration. In this review, we uncover the exciting developments and challenges in this field, analyse and explore potential solutions to these challenges and provide comments on future directions in this field.

The text attempts to analyse the GDR Ministry of State Security’s offensive operations using the instruments of radio-electronic intelligence against the PPR in 1981. The situation in Poland, the emergence of Solidarność and possible, uncontrolled spreading of a wave of democratisation onto the East Germany’s territory as well, drove the leaders of the latter state to undertake actions aimed at ensuring it access to information on the on-going situation in the PRP. Apart from the data obtained officially, they also intended to resort to independent methods for its acquisition, most of all by employing the secret services. The author focuses on just one aspects of such operations, that is, radio-electronic intelligence. Apart from describing the structure and the working methods of the MfS’ III Directorate responsible for this type of reconnaissance, he presents the guidelines received by this organisation, its modus operandi and forms of work both on the territory of the GDR and the PPR, as well as on that of the other states. He also points to the effects and all the problems resulting from implementing intelligence operations, including those in the context of official co-operation between the secret services of the PPR and GDR. According to the author, the manner of carrying out offensive MfS operations by radio-electronic intelligence allows for a certain scepticism with regard to the thesis that the GDR services had unlimited opportunities to work in Poland. Based on the available archive sources, the observation that the MfS found it difficult to process and apply information obtained as a result of the services’ operations, is warranted. The shortage of competent staff can be clearly seen and not all the available technical instruments could perform their role. What was also important was the lack of understanding at the MfS of the different philosophy of life in the PPR, which determined the reception of its image obtained from the monitoring in place. Moreover, archive searches provide circumstantial evidence indicating that the Polish counter-intelligence was aware of what type of operations were being carried out by the GDR against Poland. The need for co-operation between the MfS and the MSW in the context of the radio-electronic intelligence against other states, as well as the awareness of the risk related to the possible discovery of illegal radio-electronic operations, led to their closing down. This failed, however, to change the belief that the fundamental operating principles of the secret services are to distrust one’s partners and to protect one’s own interests.

Total war is involving all national components such as citizens, territories and national resources in order to defend territorial integrity, sovereignty, and national security from any threats. One of these threats is the act of terrorism which endangers the unity, sovereignty and security of the nation. Acts of terrorism are carried out to create a terror with ideological, political and religious motives and are carried out in vital objects of the state, the environment, and public facilities. One of the vital objects of a country that is prone to acts of terrorism is an airport, which is a place for various activities such as the movement of aircraft, people and goods. Moreover, an airport is a very important infrastructure in supporting the national defense. In this study, the researcher took Sultan Hasanuddin International Airport, Makassar, as the research site considering that several large cases of terrorism and radicalism have occurred in the South Sulawesi region. The objective of this study is to analyze the total war strategy carried out in the Sultan Hasanuddin Airport area as an effort to prevent acts of terrorism at the airport as a vital national object. The research method used is qualitative. The data have been collected from interviews, observations and literature study. The results of this research are in preventing terrorism, a total war strategy that is implemented has three components, including the ‘ends,’ which could prevent the acts of terrorism in Sultan Hasanuddin Airport and strengthen the national defense. The ‘means’ which is manifested in all national components, both government and private agencies, military, police and civil society, as well as facilities and infrastructure. The ‘ways’ which is the intelligence operations, strengthening cooperation between the military and civilians, strengthening synergy between ministries / agencies, training, counseling, completing security tools to prevent acts of terrorism.
