This monograph is a detailed introduction to the nascent and ever-evolving fields of metamaterials and nanophotonics, with key techniques and applications needed for a comprehensive understanding of these fields all detailed. These include the 'standard' and high-accuracy 'nonstandard' FDTD techniques, finite-difference frequency-domain mode solvers, the transfer matrix method, analytic calculations for dielectric and plasmonic waveguides, dispersion, Maxwell-Bloch and density functional theory, as well as design methods for constructing metamaterials and nanolasers, and quantum plasmonics. The book is intended for final-year undergraduates, as well as postgraduates or active researchers who wish to understand and enter these fields in a 'user-friendly' manner, and who have a basic understanding of and familiarity with electromagnetic theory.

Engineered Nanomaterials for Sustainable Agricultural Production, Soil Improvement and Stress Management highlights the latest advances in applying this important technology within agriculture sectors for sustainable growth, production and protection. The book explores various smart engineered nanomaterials which are now being used as an important tool for improving growth and productivity of crops facing abiotic stresses, improving the health of the soil in which those crops are growing, and addressing stresses once the plant begins to produce food yield. The book includes insights into the use of nanoparticles as bactericides, fungicides and nanofertilizers. In addition, the book includes an international representation of authors who have crafted chapters with clarity, reviewing up-to-date literature with lucid illustrations. It will be an important resource for researchers, nanobiotechnologists, agriculturists and horticulturists who need a comprehensive reference guide.

Emerging Nanomaterials and Nano-based Drug Delivery Approaches to Combat Antimicrobial Resistance focuses on recent and emerging trends surrounding nanomaterials and nano-drug delivery approaches to combat antimicrobial resistance. The relationship between nanomaterials and antimicrobial activity needs to be deeply explored to meet the challenges of combating antimicrobial resistance. The content of this book is divided into three main topic areas, including (i) how to overcome the existing traditional approaches to combat antimicrobial resistance, (ii) applying multiple drug delivery mechanisms to target multi-drug resistant microbes, and (iii) how nanomaterials can be used as drug carriers. This is an important reference source for those looking to understand how nanotechnology plays an important role in combatting disease and infection. As antimicrobial resistance threatens the effective prevention and treatment of an ever-increasing range of infections caused by bacteria, parasites, viruses, and fungi, this is a timely resource.

Humanitarian engineering is to provide disadvantaged individuals and communities with engineering solutions that improve lives and livelihoods. The provision of water, energy, food, shelter, energy and information are some of the issues targeted by this "discipline". Humanitarian Engineers could be the key towards achieving the Sustainable Development Goals. Currently, UNESCO is working to strengthen engineering education through curricula development and capacity building. It is also incorporating sustainability topics into engineering education by highlighting the need for green technology in engineering applications. The careful use of resources in a way that does not compromise the environment or deplete the materials for future generations is called sustainable engineering. Both sustainable engineering and humanitarian engineering require a highly interdisciplinary approach since they aim to improve the quality of life for all. The current book looks for the most recent challenges and approaches in the field of humanitarian engineering. A wide variety of topics that fall under the domain are technology-based solutions that tackle humanitarian problems. Pandemics, ageing of population, climate change, social inclusion, extreme poverty and hunger, maternal health and child mortality, education for all, are some indicative topics that could be addressed by technology. Early warning and alerting mechanisms for physical disasters, green engineering approaches, mobile health solutions for remote and underserved populations, are some paradigms that fall under the researched theme. The book is accepting research, real-life case studies, innovative models and approaches, and other work that lies in the presented theme. The proposed collection of chapters will provide an overview of the present thinking and state-of-the-art developments in humanitarian engineering. The book aims at providing latest research findings and their practical implementations, as well as new formulations, solutions, and case studies for tackling humanitarian contemporary issues. The book will give a unique opportunity to stakeholders, researchers and the academic community working in the aforementioned domains to understand the implications and solutions to a variety of topics. The book is anticipated to trigger further research on issues directly related to the proposed humanitarian topics.
