The precipitous expansion of ecotourism destinations and tourists has intensified competition in the tourism business. Thus, the present study investigates the connection between destination image and travel motivation that marketers must comprehend and focus on establishing ecotourism in Bangladesh. Despite a growing number of works on destination image, there has been little investigation on the relationship between travel motivation. This study aims to evaluate the effect of destination image and travel motivation on tourists’ selection of ecotourism destinations. Therefore, it utilised a structured survey aimed at visitors during their on-site experiences, unlike earlier studies that mainly focused on identifying destination characteristics. Using SPSS-SEM, the suggested structural model was evaluated using a sample of 326 tourists from various Bangladesh’s ecotourism destinations. The results confirmed that cognitive and affective destination images significantly influence travel motivation. It also indicates a better understanding of the relationship and significant managerial implications for destination marketing managers.

Introduction: Today, the demand for halal tourism has increased dramatically and highlighted as one of the new horizons and fastest-growing sector in the world’s tourism industry. Background Problem: Malaysia is indeed one of the countries with the most concerned halal segment in the tourism sector. Research Objective: The key purpose of this study is to examine the influence of affecting attributes on tourist’s behavioral intention to visit Malaysia as a halal tourism destination. Research Methods: The development of the research framework is based on the theory of plan behavior (TPB) model. A total of 394 responses were received from the Klang Valley area of Malaysia. For the purpose of analyzing the data, SPSS and AMOS was hired. Findings: Findings from the study reveal that, affecting attributes like, “Halal Certification for Food and Beverage”, “Destination Image” and “Emotional Incidents” have a significant positive influence on tourist’s satisfaction towards behavioral intention to determine the destination. Research Contribution: The key significance of this study demonstrated that a large number of Muslim travelers are able to experience Islamic cultures while considering halal tourism products and services in visiting accessible Muslim destinations. Conclusion: The conclusions of this research provided insights into the behavioral intentions of Muslim tourists select Malaysia as a destination for tourism.

Plasmonic is an emerging technology used to increase the performance of thin-film devices via light-trapping mechanisms. Recently, plasmonic devices have been used due to their nanoscale fabrication abilities. Metamaterials are promising candidates for improving the light absorption of plasmonic devices. The extraordinary properties of metamaterial-plasmonic devices (such as the perfect absorption of light) open up applications such as solar energy harvesting, photo-detecting and making batteries. This thesis focuses on the theoretical design and experimental studies of metamaterial-based perfect absorbers (MMPA) to improve their optical properties and applications (e.g., energy harvesting). I also design a high-power MMPA for high-power laser applications. First, I present the design and analysis of a high-power broadband perfect absorber. An array of rectangular patterns was placed to broaden the bandwidth so that the array can function between 950 nm and 1400 nm. Here, I propose a tungsten boride (a refractory ceramic) broadband metamaterial absorber and characterize its optical properties numerically and experimentally. I have also analyzed the damage characteristics of this absorber using a femtosecond laser and compared these with an ordinary gold metamaterial absorber. Second, a multilayer-based perfect absorber for omnidirectional capabilities is theoretically and experimentally analyzed. The device provides a reasonable amount of light absorption and thermal stability has been checked. Applying this device to high-temperature solar cell applications is discussed. I demonstrate a thermally stable broadband absorber based on an ultrathin layer of refractory ceramic, tungsten boride. I experimentally analyze and compare the performance of the absorber with an aluminum-based absorber. The multilayer perfect absorber has absorption higher than 85% in the wavelength range between 500 and 1600 nm over a large range of incident angles (up to 60 degrees). I show that a tungsten boride absorber has significantly better temperature stability compared to its aluminum counterpart, achieving stable operation at temperatures up to 270 ℃. These absorbers may have applications in solar thermophotovoltaic energy conversion. Third, a square hole structure is proposed, where a lossless silica dielectric material is combined with MnO2 materials. Then, the geometric parameters of this structure are numerically optimized at the desired application. An adequate choice of parameters, shape and the proper combination of materials can lead to an electrically tuneable metasurface. The structure can produce a 25% change of transmission with the applied electric power. Finally, I numerically analyzed and experimentally characterized Kevlar fabrics for the application of personal heat management. Heat management is essential for human comfort. In recent years, passive radiative cooling through heat transfer to outer space has been extensively studied. Personal temperature control is used to control the temperature of objects beyond the local environmental temperature. I show that Kevlar fabrics are transparent to mid-infrared human body radiation but opaque to visible light. Here, I have experimentally investigated the optical and thermal properties of Kevlar fabrics, which can have 90% emissivity in the mid-infrared region and produce a 2.6 ℃ temperature drop. I processed a Kevlar textile that promotes effective radiative cooling while retaining sufficient air permeability, water-wicking rate, and mechanical strength for wearability. The Kevlar fabric is an effective and scalable textile for personal thermal management.
