Book Description
This lecture presents the perfectly matched layer (PML) absorbing boundary condition (ABC) used to simulate free space when solving the Maxwell equations with such finite methods as the finite difference time domain (FDTD) method or the finite element method. The frequency domain and the time domain equations are derived for the different forms of PML media, namely the split PML, the CPML, the NPML, and the uniaxial PML, in the cases of PMLs matched to isotropic, anisotropic, and dispersive media. The implementation of the PML ABC in the FDTD method is presented in detail. Propagation and reflection of waves in the discretized FDTD space are derived and discussed, with a special emphasis on the problem of evanescent waves. The optimization of the PML ABC is addressed in two typical applications of the FDTD method: first, wave-structure interaction problems, and secondly, waveguide problems. Finally, a review of the literature on the application of the PML ABC to other numerical techniques of electromagnetics and to other partial differential equations of physics is provided. In addition, a software package for computing the actual reflection from a FDTD-PML is provided. It is available here.

Book Description
Anna Olsen knows it's time to leave her sister's increasingly crowded house and start a life of her own. Following her sisters' examples, she becomes a mail-order bride, and after a short correspondence with clock maker and jeweler Edward Parker, she moves to Denver to become his wife. Almost immediately it's painfully apparent that Anna and Edward are very different. Anna is a free spirit who would rather be painting and enjoying the company of friends than cleaning house. Edward is a consummate perfectionist who, on their wedding day, hands Anna a list of chores that need to be done around the house daily. Can this mismatched couple see past their differences to a harmonious future? Or will their disparate passions create obstacles neither is willing to surmount? Maggie Brendan closes her Blue Willow Brides series with a heartwarming tale of true love despite misunderstanding, showing readers that God's timing is always perfect.

Book Description
THE MATCHMAKING CHEF COLLECTION The eight Matchmaking Chef novellas When Suzie Matthews (Bed, Breakfast & You) accidentally cooks up a scene that causes her sister to get back together with her high school boyfriend (Home for the Holidays), she wonders if she can help other singletons living in the small mountain town of Legend, Tennessee find the loves of their lives. Being a matchmaker isn't really on her list of things to do--after all, she has a bed & breakfast to run, cookbooks to write, and a television show on the Food Channel to keep up with. But baking is her thing, and perhaps matchmaking can be her thing, too. After all, there is a song going through her head that goes something like this... Matchbaker, Matchbaker, bake me a match? No wait. Make me a match. Nevermind! You get the picture, right? Welcome to Legend, Tennessee. And welcome to the matchbaking, er, matchmaking world of Chef Suzie Matthews.

Book Description
The heat is on... When Boston psychic Lucy Valentine finds herself involved with a group of eccentric mediums trying to fine tune their abilities, she is convinced a rare spring heat wave has flushed all the local crazies out of hiding. Adding to her theory is her newest client in the Lost Loves division of Valentine, Inc., her family's lucrative matchmaking firm. He's an animal whisperer who hires Lucy to locate his soul mate?because his cat told him so. Finding his purrfect match, however, isn't as easy as it seems. But craziest of all is the Beantown Burner, a serial arsonist who is targeting private eye Sam Donahue, brother of Lucy's boyfriend, Sean. With the help of her kooky psychic group, Lucy must tap into hidden abilities to catch the firebug before the fires turn deadly. She never expected to discover that the motive behind the flames hits a little too close to home...and dangerously close to her heart.

Book Description
Cassia has always trusted the Society to make the right choices for her: what to read, what to watch, what to believe. So when Xander's face appears on-screen at her Matching ceremony, Cassia knows with complete certainty that he is her ideal mate . . . until she sees Ky Markham's face flash for an instant before the screen fades to black. The Society tells her it's a glitch, a rare malfunction, and that she should focus on the happy life she's destined to lead with Xander. But Cassia can't stop thinking about Ky, and as they slowly fall in love, Cassia begins to doubt the Society's infallibility and is faced with an impossible choice: between Xander and Ky, between the only life she's known and a path that no one else has dared to follow.

Book Description
The term photonics can be used loosely to refer to a vast array of components, devices, and technologies that in some way involve manipulation of light. One of the most powerful numerical approaches available to engineers developing photonic components and devices is the Finite Element Method (FEM), which can be used to model and simulate such components/devices and analyze how they will behave in response to various outside influences. This resource provides a comprehensive description of the formulation and applications of FEM in photonics applications ranging from telecommunications, astronomy, and sensing, to chemistry, imaging, and biomedical R&D. This book emphasizes practical, problem-solving applications and includes real-world examples to assist readers in understanding how mathematical concepts translate to computer code for finite element-based methods applicable to a range of photonic structures. In addition, this is the perfect support to anyone using the COMSOL Multiphysics© RF Module.

Book Description
This valuable resource summarizes the past fifty years' basic research accomplishments in plasma dynamics for aerospace engineering, presenting these results in a comprehensive volume that will be an asset to any professional in the field. It offers a comprehensive review of the foundation of plasma dynamics while integrating the most recently developed modeling and simulation techniques with the theoretic physics, including the state-of-the-art numerical algorithms. Several first-ever demonstrations for innovations and incisive explanations for previously unexplained observations are included. All the necessary formulations for technical evaluation to engineering applications are derived from the first principle by statistic and quantum mechanics, and led to physics-based computational simulations for practical applications. The computer-aided procedures directly engage the reader to duplicate findings that are nearly impossible by using ground-based experimental facilities. Plasma Dynamics for Aerospace Engineering will allow readers to reach an incisive understanding of plasma physics.
