The proposed unit cell has band stop response ranges from 3.3 GHz to 10.5 GHz. The UWB SC antenna with an FSS reflector demonstrated an improvement in gain from 2 dB to 5 dB in the lower band and from 4 dB to 8 dB in the upper band. The overall size of FSS based antenna is $62.5text{mm}times 62.5text{mm}times 1.6$ mm.

Also, it has led to a massive increase in energy consumption. Although the power requirement of the optical network is low, gradually the trend is shifting to all-optical networks, and very soon the high demand for optical networks everywhere will lead to book significant overall consumption. The proposed architecture not only supports the growing demand for bandwidth but also makes it energy efficient by using artificial neural networks. ANN algorithms are used to predict the traffic flow of a network and hence smartly switch the transmitting module ON and OFF in order to save power consumption. Traffic prediction is access network dependent and therefore can adapt to the changing pattern of different environmental conditions.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"20 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"115453526","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, due to the limited bandwidth of PPM receiver, detecting very short pulses could be challenging. The electrical pulse expansion can be applied to overcome this limitation. This is especially important in ultra-high precision timer applications in PPM signal demodulation. The paper discusses the radio frequency (RF) low-pass filter (LPF) application for pulse expansion purposes. Analytical and experimental results demonstrate the expansion of electrical pulses having 50 ps duration at full width at half maximum (FWHM) using several types of LPFs. The impact of the filter parameters on the PPM pulse shape, amplitude, and duration is discussed.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"9 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132369850","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The reconfigurability is achieved using PIN diodes. When the diodes are switched from the OFF to the ON state, two stopbands operating at 5.2 and 5.9 GHz become passbands, and the passband at 4 GHz turns into a stopband. The proposed structure with multi-band characteristics provides stable performance at incident angles up to 60 degrees with TE and TM polarizations under the OFF and ON states of PIN diodes.

One solution to this problem is Software Defined Network (SDN) stack, which allows programmable configuration for the network. Decoupling the data plane (packet forwarding) from the control plane (routing process) in the standard TCP/IP networks depicts the basic idea of SDN. The main component of the SDN is called a controller. Various controllers can work on SDN, e.g., Floodlight, Open Day Light, RYU, and POX. Controllers perform best depending on the application running because each application can have different requirements from other applications. In this paper, we compare the POX and RYU controllers in terms of their impact on SDN performance. We chose these two controllers, first, because they are open-source and commonly used for SDN network performance studies, and second, because they use a clean and convenient python based configuration environment. We used the open-source emulator Mininet to conduct our experiments on various network topologies. We find that the RYU controller outperforms the POX in most simulated scenarios.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"2003 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127318244","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

There is a rather limited choice of available techniques for monitoring the change in a polarization state of an optical signal over the transmission line. Mostly, as the typical measurement, the total optical line polarization mode dispersion (PMD) is determined, or the instantaneous change in polarization state at the line input or output is measured. But that does not allow determining the location and cause of sudden polarization changes in an optical fiber. The authors propose a polarization monitoring technique using a traditional commercially-used optical time-domain reflectometer (OTDR) with additional circuitry to generate polarization-dependent measurement traces. Such a technique can potentially be used for continuously tracking a physical impact on an optical fiber link.","PeriodicalId":426797,"journal":{"name":"2022 Workshop on Microwave Theory and Techniques in Wireless Communications (MTTW)","volume":"5 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2022-10-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114793694","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
